Jul.9 (GMM) Following the Italian marque's dreadful British grand prix, Luca di Montezemolo says he does not want to see any more "stupid mistakes" in Ferrari's 2008 title defence.



Team boss Stefano Domenicali last Sunday admitted Ferrari committed performance, strategy, driver and even weather forecasting errors throughout the rain-affected Silverstone race.



Brazilian driver Felipe Massa spun at least five times, finishing two laps down and dead last.



"We can not commit any more stupid mistakes as we did last Sunday if we want to win the world championship," Montezemolo, Ferrari president, told Italy's La Gazzetta dello Sport.



"Naturally it was unpleasant to watch a race such as ours, but I hope it will serve as a lesson to my guys -- and I have no doubt that it will be the case," he added.



Montezemolo said Sunday's errors were not the first this season.



"We are in the lead in the championship, but we missed too many opportunities altogether, so we cannot afford any more."
