Schumacher not sure he would have won in Vettel's car 3 January, 2013 Jan.3 (GMM) Michael Schumacher’s comeback would have been far more successful at the wheel of a top car, according to F1 boss Bernie Ecclestone. “If he had had a Red Bull or a Ferrari, Michael would have won again,” the F1 chief executive told Italian newspaper Corriere della Sera. “He should have demanded more guarantees, because it was his [Mercedes] car [to blame] and now his reputation has been tainted,” added Ecclestone. In a new interview with Germany’s Auto Motor und Sport, Schumacher – who turns 44 on Thursday – didn’t want to say that he would have definitely won races in a Red Bull. The seven time world champion said: “I would agree that if I was in a car like that, I would be running with those [top] guys. “Whether I would win races in the current Red Bull or McLaren is a good question,” said Schumacher, who won a record 91 races in his ultra-successful first career. “You don’t just get in a car and win immediately. Could I go as fast in a custom Vettel car as I could in a custom Schumacher car? Probably not,” he admitted. Subbed by AJN.
