According to Autosport, after impressively whittling down the gap Alonso had opened up behind him, Perez (pictured above in the parc ferme with Ferrari team principal Stefano Domenicali) received a radio message from Sauber strategists advising him to be careful. Shortly thereafter, Perez went wide off the track and lost Alonso. The young Mexican pilot still finished second – an unprecedentedly strong finish for Sauber – but many wondered if the message wasn't a code passed on from Ferrari, which supplies Sauber's engines.
Of course, Sauber, for its part, is denying the rumors, but it wouldn't be the first time in F1 that a leading team had told a midfield or back-marker team to which it supplied engines to reel in one of its drivers in the interest of preserving the front-runner's position. We'll probably never know the truth, but one thing's for sure: Perez is a rising talent in Formula One, and Alonso had better get used to watching out for him.
