Horner: Red Bull team now best in world

That is the view of its boss Christian Horner, who reckons the work that helped it clinch both the constructors' championship and the drivers' crown with Sebastian Vettel is all the proof that is needed about how good the outfit is now.

"It is a big performance from the team," said Horner about its efforts in 2010. "This team has come of age this year. It is a very young team and I am just very proud to represent them - today I believe they are the best team in the world."

Horner says he is overjoyed about the way the season ended for his team - and reckons every member of the Milton Keynes-based outfit deserved praise for the efforts of this season.

When asked what it meant to him personally to have won both titles, Horner said: "The last one hasn't really sunk in yet, so this time will take a little bit of time as well. It is a very special feeling and it was fantastic to have Mr. [Dietrich] Mateschitz here to see our first drivers' world champion.

"We have had tremendous support from Red Bull, from Dietrich, and I know the excitement that will be in Milton Keynes and the surrounding area, from every single member of the team who has put everything into this championship. It is thoroughly deserved and it is a very proud team."

Horner said the team did not want to celebrate the title success the moment Vettel crossed the line - as it wanted to wait until it was guaranteed that Alonso could not take the fourth position he needed to claim the title.

"I spoke to 'Rocky', his [Vettel's] engineer, the lap before and said I would not speak to him until we know what the result is," explained Horner. "As soon as Rosberg crossed the line we knew it was his and it was a very emotional moment.

"It has been a tough season for both our drivers. They have both driven phenomenally well, they have taken the championship down to the wire and either one of them could have won it this year.

"They both had their time, Sebastian has led this championship once and that is after Abu Dhabi, which is the most important time to lead it. So we are very, very proud of what he has achieved."
