LONDON, England - Formula 1 chief executive Bernie Ecclestone has admitted he would be happy if Red Bull's domination of Formula 1 race ends in 2013.The team has won every Drivers' and Constructors' title for the past three seasons (2010-12). Ecclestone said: "It wouldn't be too bad a thing if we were to have a change at the top of the sport, perhaps with Ferrari leading the way again." As for his relationship with Ferrari's president Luca di Montezemolo, which after a recent spat appeared to be irreparably damaged, Ecclestone insisted: "Montezemolo is still a friend and I'm convinced he didn't really intend to say the things he said about me. I'm happy - it's just role-playing!"FAVOURING FERRARI?The Ferrari president attacked Ecclestone after the F1 chief said the overtaking scandal, in which Ferrari claimed Sebastian Vettel had overtaken Jean-Eric Vergne illegally, was "a joke" and "not Ferrari-like".Montezemolo said: "You have to show respect for your elders, especially when they get to that stage in which they are no longer in control of what they say."However, old age is clearly incompatible with certain roles and responsibilities."Ecclestone denies he has made a strategic decision to side politically with Red Bull over Ferrari: "All I said was that Red Bull deserved to win the titles again and that I didn't agree with the stance Ferrari was taking with the appeal against the alleged rule infringement by Vettel at Interlagos."Red Bull has done a lot for the reputation of our sport."BRIBERY SCANDALEcclestone admitted that, if he was charged by German prosecutors over the Gribkowsky bribery affair, he could be forced to step down. He said: "I would be (worried) if I were guilty! Are they trying to entrap me? I don't know and I don't care. All I know is that people try anything when money is involved."Ecclestone denied he feared F1 would fall apart if he was no longer in charge. "I've said that F1 would have been different without me. I don't think it would be better. Is there a new Ecclestone on the horizon? No, I don't see one." He concluded by saying that his "dream team" in F1 would feature Vettel and Lewis Hamilton as team mates.
