Horner added that Vettel's third successive title, and the fact he is now the youngest triple champion in the history of the sport, meant the German can now be classed alongside some of F1's greats.
“He is a three-time World Champion and has won successive World Championships,” he said. “He has raced in 101 races and won 26 of them, he has been on the podium more than 40 times which is almost in fifty per cent of the races he has raced in, and he has 34 pole positions. I think those statistics, plus the way he conducts himself, just absolutely puts him amongst the greats.
"F1 at the moment is going through a halcyon period. Fernando Alonso is a wonderful, massively-gifted driver, as is Lewis Hamilton, and then you have the likes of Jenson Button, Kimi Raikkonen, who has come back this year, and of course Mark Webber, so it's a halcyon period for F1 and to succeed, and achieve the level of success that he has, is quite remarkable, especially as he is only just 25 years of age."
