Berger: Vettel will win championships

Berger, who won the Italian Grand Prix for Ferrari 20 years ago to the week, was teammates with two world champions - Ayrton Senna and Nigel Mansell - during his Formula One career and recognises the same kind of qualities in his driver.

"Sebastian proved today he can win races," said Berger. "But he is going to win world championships. He is very good."

Berger, who has tasted victory in F1 as a driver and an engine supplier with BMW in the past, also said that the emotion of winning for the first time as a team owner is a new one.

"It's an unbelievable feeling," he said. "We've been extremely lucky to have the support of Red Bull for the basics of the car - it helps a lot. We have been building a nice little team."

The Austrian added that there would be further discussions with Red Bull regarding the future of his team, which is gearing up to become a full-blown constructor in 2010 but is also up for sale.

"We'll speak again about that tomorrow," he said.
