Ferrari president Luca di Montezemolo has spoken out against the booing which was targeted at Sebastian Vettel at Monza and other races.

The Italian Grand Prix was the latest in a series of races where Vettel has been the focus of booing from parts of the crowd.

“Maybe it would have been better, if there had been fewer boos for Vettel: congratulations to him and to Red Bull,” said Montezemolo at the Frankfurt Motor Show, “but to our critics and those with short memories, I would like to remind them that in the past few years, Ferrari has always been at the top.”

Vettel’s team mate Mark Webber also criticised the jeering directed at his team mate, saying: “the atmosphere I was not completely a fan of, to be honest”.

Montezemolo said Ferrari were not ready to surrender their chances in the world championship: “There are still a lot of races to go and we must never give up, right to the final kilometre.”

“I think that it will take an enormous effort from everyone, but we must have a competitive car. I have said it before and I say it again: I want to thank the fans, who have shown so much affection and understanding and this must push us to do even more.”

Montezemolo added ?����?�2bn (?�?�1.69bn / $2.65bn) will be invested in Ferrari’s activities over the next five years, excluding its Formula One operation.
