Renault's flamboyant team principal Flavio Briatore has said that he will leave Formula One in two years' time.

Asked if he would ever work for champions Ferrari, Briatore said: "I like to beat Ferrari but when my team doesn't win, being Italian, I obviously support Ferrari.

"But I don't think I will go to work at Maranello, especially as in two years I will stop."

Briatore also hailed Formula One's agreement to cut costs during the global financial crisis.

"The new rules will make Formula One more exciting and human," he predicted. "I agree that the constructors, in order to try to avoid the crisis, have given a good example by trying new ideas."
