Christian Horner, Red Bull-Renault (Team Principal):
“A phenomenal drive by Sebastian today. We had a communication problem with the first stop, which affected both drivers as they were both stopping on the same lap. It delayed Sebastian, but we managed to re-adjust our strategy. We didn't panic and managed to engineer ourselves out of the situation to get him back into the lead. He then had an awfully long way to go on the harder tyre, which he made work. He soaked up huge pressure from Fernando and Jenson and then our hearts were in our mouths when the accident happened just in front of him. But he picked his way through that and, with the benefit of the option tyre, was able to have a bit more comfort in the remaining laps after the re-start. It was a classy drive from Sebastian today and a tremendous team performance to recover from what looked to be a difficult first stop to win the race.

“At one stage Mark was 15th after the first round of stops, but he never gave up and kept on pushing through. He pulled a great move on Kobayashi on the last couple of laps who's not an easy guy to pass and it was a shame not to have him on the podium today, as he deserved to be there.”

Cyril Dumont, Red Bull-Renault (Renault Engineer):
“Once again it was a really good result for Sebastian and it could be worse for the start of the season – five out of six wins! I don't know where we have to go back to, to see these kind of results. Regarding Mark, it was a bit chaotic in the first pit stop, but it was a great recovery and nice to see him finish fourth. It's hard to overtake on this track, but he did it. Overall we had a great result this weekend, we scored more points than our opponents and it's a great start to the season.”

Stefano Domenicali, Ferrari (Team Principal):
“Going into this weekend, if we'd been told that we would finish second, eleven tenths off the winner, I would have signed up for it on the spot, but now there's no denying there is a slight feeling of regret. Fernando was fantastic all weekend long and today he fought for the win, right down to the final metre. The race had a deserving winner, but there's no doubt the red flag towards the end deprived our driver of the opportunity to attack in the final laps, making the most of having tyres with slightly less degradation. At the restart, with everyone on new tyres, there was not much more we could do. There's much regret for Felipe too, who was also capable of getting a good finish: the collision with Hamilton pretty much put him out of the running and then he immediately ended up in the barriers. It is only a week on from when we were lapped at the Catalunya Circuit and we have seen how quickly things can change, depending on the track characteristics and the type of tyre we are using. Clearly, the situation in both championships is getting ever more difficult, but we are not giving up: we are coming up to two races where, on paper, we should be competitive and then, before the summer break, we will see where we stand.”

Pat Fry, Ferrari (Technical Director):
“It was an incredibly close race from the first to the last lap. After we managed to sort out Fernando's car, which had not been as quick in yesterday's qualifying as it had been in free practice, today we showed a good race pace on both types of tyre. I think we took the right decisions at the right time at every point in the race, making the most of our opportunities. When the race was neutralised after Felipe's accident, we chose to change tyres on Fernando's car, so as to put him in the right condition to attack in the final stages. Unfortunately, there was a red flag which meant the Spaniard could not try all the way to the end, but that's Monaco for you and you have to accept that anything can happen. As for Felipe, we have to work out why his DRS was not enabled by the FIA electronic control in the first part of the race, because maybe, if everything had worked properly, he would have managed to get past Rosberg sooner and not lose so much ground to the leaders. A shame, because I think he also had the potential to run a good race all the way to the end. Now we go to Canada, wanting to continue to improve our performance. There will be some new parts on the car: we must continue to push on the development front in order to reduce the gap which still separates us from the best.”

Martin Whitmarsh, McLaren-Mercedes (Team Principal):
“Our car had a lot of pace here in Monte-Carlo today – race-winning pace in fact – and I guess we'd therefore have to count ourselves as a bit unlucky not to have been able to convert that pace into the race win it could well have achieved. We selected a three-stop strategy for Jenson – and, had the race not been red-flagged just as Jenson had caught Sebastian and Fernando, I think that that selection would have been revealed as the right one. Now, of course, we'll never know – but it's undeniable that Sebastian and Fernando were both on very worn tyres at the end, whereas Jenson's were pretty fresh by comparison, so we definitely fancied his chances of being able to press home that advantage by overtaking the Ferrari and the Red Bull in the final laps. But, as I say, the red flag scuppered those chances. Having said that, Jenson drove not only faultlessly but also very, very fast here this afternoon. Indeed, he posted the team's 10,000th lap in the lead of a grand prix today, a stunning statistic. On his charge, he caught the Sebastian-Fernando battle by almost two seconds per lap whilst still managing to conserve his tyres. It was a truly excellent performance.

“Lewis, by contrast, had a frustrating afternoon. I guess the reality is that, if you start anywhere other than at the front of the grid here in Monte-Carlo, you're always going to run the risk of getting involved in incidents – especially if, like Lewis, you're a forceful driver who never, ever, gives up. But that's Lewis. That's why he's such a fantastic driver – and that's why watching him race is so thrilling. So, yes, he's disappointed, because he's been seriously quick all weekend here, but that's Monte-Carlo; that's racing; that's life. Immediately after the race he was very down, and during a post-race TV interview he made a poor joke about his penalties that referenced Ali G. However, I'm pleased to say that he chose to return to the track a little while later to speak to the stewards about the joke. They accepted his explanation.

“In summary, then, Sebastian was probably a bit luckier than Jenson today, but he drove well to win so congratulations are due. In Montreal, though, let's hope it's our turn to have a bit of luck on our side.”

Peter Sauber, Sauber-Ferrari (Team Principal):
“Once more Kamui drove a fantastic race, managing the tyres very well, and the car was strong too. This is a result he has deserved for a long time. My compliments to Kamui, and also a big thank you to the whole team who prepared the car perfectly. I now hope we can start in Montreal with our regular driver pairing.”

James Key, Sauber-Ferrari (Technical Director):
“As always in Monaco, a very eventful race for all concerned. We entered just one car for Kamui with Sergio not racing. Our hopes really relied on Kamui. We opted to go for a one stop strategy, starting on the new soft tyres, and we had a new set of super soft for the second stint. Fundamentally Kamui drove a good race. It's great to bring points home in what has been a very mixed weekend, both in terms of performance and emotion with Checo's crash. We can dedicate these points to him as a team and hope that we can get back to normal in Montreal.”

Vijay Mallya, Force India-Mercedes (Team Principal):
“Today's race was full of excitement, drama and great racing. With Adrian I believe we judged the strategy perfectly and his seventh place finish is a great reward for the whole team. He did an excellent job to keep his tyres alive in the middle part of the race when we were planning to do a one-stop strategy. Towards the end of the race we got a little bit lucky with the safety car, but we reacted well and Adrian kept pushing hard to score six important points. Paul's race was looking promising in the early laps until he picked up some damage after contact with the Toro Rosso. He was maybe a little over-eager to get by, but this was his first Grand Prix at Monaco and he will learn from this experience.”

Eric Boullier, Renault (Team Principal):
“It was a bit of a disappointing day to be honest. First of all we are glad to report that Vitaly is ok and he has no fractures. He has a sore ankle, but he is already joking and we expect the hospital to release him within the next couple of hours. With regards to the race result itself, there is disappointment because we could have finished P4. We had fresher tyres than Sutil and Kobayashi and so could have caught them, but they managed to pit when the safety car was called. Nick moved back up to tenth position, which was not bad and finishing eighth was ok given the position he started in. However, there was an opportunity to score more points.”

James Allison, Renault (Technical Director):
“After a disappointing weekend during which we struggled to find a decent qualifying pace, we managed to bring some points home. More importantly, Vitaly is OK and this is a relief for the whole team. We elected to go for a one-stop race in order to step ahead of the cars in front of us and this strategy seemed adequate a few laps before the end of the race, as both R31s were in the points. Unfortunately, Vitaly has been caught up in the crash involving Adrian Sutil and Jaime Alguersuari. There are not a lot of positives to be taken from this weekend, but Nick moves up one place in the drivers' championship and we have extended our lead over Mercedes GP in the constructors' classification. This said, we're under no illusions and we know we must raise our game in order to perform at the level we want to.”

Riccardo Penteado, Renault (Engine Support Leader):
“First of all it's great news to hear that Vitaly is OK after a heavy impact with the barriers. Until that point he was looking like scoring some decent points but the most important thing is to know that he hasn't got any serious injuries. Nick finished in eighth after a busy race, which is good considering his starting position after a disappointing qualifying. It was a great team effort to gain so many positions and even though we would have expected more on previous form this season, it's a good result this weekend. We have, however, extended our advantage over Mercedes, which overall can be considered a good overall outcome.”

Sam Michael, Williams-Cosworth (Technical Director):
“It was a good result to get some points on the board. It was close to being a lot more but that is the nature of Monte Carlo. Pastor has driven outstandingly all weekend, so it is a shame that his race ended in the barriers. The tyres were solid all afternoon but it became clear that it would be a two-stop race strategy for us. The safety cars both hurt us as well as we lost a lot of time with both drivers. On the positive side, we didn't have any reliability issues and we're looking to continue developing the car ahead of Canada.”

Franz Tost, Toro Rosso-Ferrari (Team Principal):
“Another very exciting Formula 1 race, with action from the very beginning to the end, including a re-start. On top of that, the top three finished within 2.3 seconds, having each gone for different strategies – a one stop, a two and a three, which shows how complex it is to find the best strategy these days. From the Toro Rosso point of view, the whole team did a good job as we come away with one point, which was better than we could have expected after a rather disappointing qualifying performance yesterday. Sébastien Buemi did a very good job, not making any mistakes which is not easy at Monaco, eventually finishing six places higher than his grid position.

“Jaime Alguersuari was unfortunately involved in the accident that brought out the final safety car and then the red flag. He had nowhere to go and he could not avoid it. Now, we must analyse why our qualifying performance was not good enough, whereas our race pace was better. For the next two races, we will have the same Soft and Supersoft Pirelli tyres, which suggests that Montreal and Valencia should also produce some exciting racing.”

Ross Brawn, Mercedes (Team Principal):
“We felt confident after qualifying and practice that both drivers would have some good opportunities today but clearly it turned out to be a very disappointing race. The difficulties that we experienced on the first set of tyres, with the super softs falling away from us and graining so early, really dictated our race. We need to look into it as this was surprising after the good pace we had during the practice sessions. We had a few technical problems with the cars in the race but the core issue was the inability to make the first set of tyres last more than ten or twelve laps.”

Norbert Haug, Mercedes (Daimler Representative):
“These were not the results we wanted here in Monaco. Nico's accident on Saturday morning, from which he thankfully escaped unhurt, was certainly a handicap for us, but our guys did a fantastic job to build the car up in record time ready for qualifying. Michael started fifth but did not make a good getaway and the reason for this will be investigated. As a follow-up, his front wing was damaged in contact with another car at the first corner and this badly handicapped his performance in the first stint. After his pit stop, with a new nose and another set of option tyres, his lap times looked better, but an airbox fire stopped his race when he was about to pit during the first safety car period. In addition to a car that was not handling well, Nico suffered some KERS problems during the race and finished outside the points. Despite the lack of results, I would like to thank everybody in the team for their hard work and dedication throughout a difficult and challenging weekend. We will do a better job in Montreal.”

Thierry Salvi, Lotus-Renault (Renault Sport F1 Support Leader):
“I think that is a very good result for us, the best finish of the year for both cars. The car setup and strategy was good for both drivers and we are very satisfied with what we have achieved this weekend.”

Mike Gascoyne, Lotus-Renault (Chief Technical Officer):
“A strong result for the team and it was good to get both cars over the finish line. Both drivers drove very strong races and we gave them a chance to fight with a two stop strategy, starting both cars on options. We switched Heikki to the prime for the last two stints because he had higher degradation but kept Jarno on the options until the second pitstop and even thought they were held up by slower cars we are very pleased with 13th and 14th.”

Tony Fernandes, Lotus-Renault (Team Principal):
“I watched the race from Bali and that capped off an incredible week for us. This time last year neither car finished the race but today both cars crossed the line in 13th and 14th places. Our pace was good but most importantly both cars finished the race, we brought the Team Lotus brand home and we won the first of the GP2 races in Monaco. That constitutes a very good weeks work at the office. Now we go to Montreal and as we keep moving forwards to the rest of our history, our heritage and our destiny with Caterham. Thank you all for one hell of a ride.”

John Booth, Virgin-Cosworth (Team Principal):
“We predicted yesterday that the race would be incident-filled and that we would need to be ready to take advantage of any opportunity that came our way, and this is exactly what both drivers did today. It was a difficult decision to start both cars on a split strategy, but one that ultimately paid off at different stages in the race. We had information from Timo's first stint on the Option tyre that made us feel confident that, when the safety car came out, we could switch Jérôme to a one-stop and take the track position that we were getting from the strategy. Jérôme had done a great job of defending against Lotus for around 15 laps but unfortunately, due to running wide for a blue flag, he picked up some marbles and was unable to stay in front. Timo drove a strong first stint to keep in touch with the guys in front. Throughout the weekend he has demonstrated great skill and faultless performances but unfortunately we believe his right rear push-rod failed in the race, so we will go away and analyse what led to that. All in all it has been a challenging but rewarding couple of weeks of back to back racing and we will return to our base to prepare for the trip across to Canada in two weeks' time.”

Colin Kolles, HRT-Cosworth (Team Principal):
“It has been a very tough weekend for the team but everybody worked very hard to achieve the best possible result under the circumstances. We suffered the whole weekend with balance problems and, due to the reduced amount of running, were not able to get the best out of the car. Both drivers finished the race though, which is very important. No we must look ahead to Canada where we're planning to introduce new updates which should improve the performance of the car.”

Paul Hembery, Pirelli (Motorsport Director):
“We were privileged to see one of the closest ever battles for victory in Monaco: the most prestigious race of the year. The top three used completely different tyre strategies but came out more or less together, which is exactly what we were aiming for at the start of the year. It's great to see the tyre strategy forming such a prominent part of the action; giving us a fascinating battle for the lead where any of the top three drivers would have been very deserving winners. Had it not been for the red flag in the closing stages, I'm sure that their fight would have continued all the way to the very end. It was also great to see some of the other drivers scoring points such as Kobayashi, Sutil, Buemi and Barrichello. With the fastest-ever qualifying lap of Monaco yesterday and some drivers going for more than 50 laps on the PZero Yellow today, Pirelli has supplied both performance and adaptability with this year's Formula One tyres.”
