Sebastian Vettel: His rivals react

Victory in the Indian Grand Prix was more than enough to see Sebastian Vettel crowned F1 champion for the fourth successive season - making him only the fourth driver in history to have four titles to his name.

On the back of his success, figures within the paddock reacted to the German's latest championship crown...

Mark Webber:
Well done to Seb on his Championship and also to all the Team; to get a fourth title is amazing. It's been a great job by the whole team to achieve the title four years on the trot and it has once again set itself as the benchmark for the others.

Christian Horner:
For Sebastian to have joined the illustrious names of Fangio, Prost and Schumacher is an incredible achievement, especially at such a young age and it's a privilege to work with him.

Adrian Newey:
Sebastian must now be considered one of the all-time greats. He makes mistakes sometimes, but he always learns from them; he's very humble and the success and fame he has achieved over the last few years has never gone to his head; he remains with both feet firmly on the ground.

Nico Rosberg:
A great job from Sebastian today and his fourth title is well deserved. He has done an amazing job. We will do everything possible over the winter to be competitive next season.

Lewis Hamilton:
Massive congratulations to Seb on becoming four-time World Champion today. That's an awesome achievement and he's put in some incredible performances this season. I really hope we get to take the fight to him next year!

Ross Brawn:
Congratulations to Sebastian Vettel on winning his fourth World Championship. To win multiple championships as he has done, you must be not just a driver but also a fantastic team member, and he clearly has all the attributes that requires. It's now up to us to stop him.

Toto Wolff:
Congratulations to Sebastian Vettel on his fourth consecutive World Championship. He has done a perfect job since the summer break and this is a richly deserved title.

Fernando Alonso:
I congratulate Sebastian Vettel. They have been very strong and dominant, especially in the second half of the season and Red Bull deserve to be champions. We need to start thinking about next year and make things more difficult for him.

Felipe Massa:
I want to congratulate Sebastian, who deserves everything he has achieved so far. I am really happy for him, because he is a great driver and a very nice guy. From today, his name will sit alongside the greatest drivers in the history of Formula One, such as Senna, Schumacher and few others.

Stefano Domenicali:
It's right and proper to congratulate Sebastian and Red Bull for their fourth consecutive world title. These are moments that we are well aware are extraordinary, but obviously, we hope that all the hard work we are doing aimed at the future, will be able to interrupt this run of success.

Jenson Button:
Congratulations to Seb for winning his fourth world championship. That's very impressive - especially to win four in a row. His team did a great job, Adrian Newey demonstrated how good he is, and Seb finished it off nicely with a win.

Sergio Perez:
I want to say big congratulations to Sebastian. He's shown over the past few years that he's a truly great champion. He's had a great season; what he's achieved is incredible. Now, I really hope we can fight against him next season!"

Martin Whitmarsh:
Congratulations to Sebastian today. He once again drove faultlessly to put the title beyond the reach of his closest rival. To win four world titles - particularly four in a row - is incredibly impressive stuff. He'll have a few days to enjoy this achievement, but it's a mark of his relentless competitiveness that I'm sure he'll be fighting for victory in Abu Dhabi in a week's time.

Adrian Sutil:
Congratulations to Sebastian for winning his fourth world championship! He deserved it!

Monisha Kaltenborn:
Congratulations to Sebastian Vettel and Red Bull for winning the World Championships.

Jean-Eric Vergne:
What he's done is something truly special, so congratulations.

Phenomenal! Particularly since the summer break, when he grabbed the title and never let anyone else look at it.

I want to congratulate Vettel with his fourth world championship!! Well done my friend!

Alain Prost - Renault ambassador:
I'm delighted to see Sebastian win the title today. He is a great driver and he has had some outstanding wins this year, some of the best of his career so far. Singapore was one of those wins: he was fighting all the way but he made it look easy, which is always a mark of a worthy winner. You can see he is methodical in his approach, builds a strong team around him that is 100% motivated for success and is entirely focused on the end result. He is a great champion and I don't think this title will be his last. He has a good team around him, stability with the technical team and with Renault, and of course he is still young enough to challenge for more. I'm pleased to see him equal my four titles. I wish him all the best to go on and win others and become a great Renault champion.

Jean-Michel Jalinier - President of Renault Sport F1:
Congratulations to Sebastian on his fourth title. He has shown great panache this year against very tough competition and fully deserved to win this season. It is a proud moment for Renault too, as Sebastian has taken the number of drivers' titles we have to which we have contributed to 11, five of which have been won with the Renault V8 engine. We are very incredibly proud to have been able to maintain our quality and success throughout this entire period and to give great drivers like Sebastian the opportunity to do justice to their innate talent.

Jens Marquardt - BMW Motorsport director:
Congratulations to Sebastian Vettel on his fourth World Championship title in a row. He continues to take his place as one of the greats of the sport," said BMW Motorsport Director Jens Marquardt. "Even as a BMW Junior, his immense talent was clear to see. His record of 18 wins from 20 races during the 2004 Formula BMW season remains unbeaten. We are pleased to have been able to support Vettel on his way to being Formula One World Champion. He still enjoys a good relationship with BMW Motorsport.
