Sunday 5 Oktober at 22:18 : Dietrich Mateschitz has hinted he might reconsider his earlier pledge to sell his 50 per cent share in the formula one team Toro Rosso.

With the customer car saga possibly back in a state of flux, and Sebastian Vettel's breakthrough Monza win, the Red Bull mogul told an Austrian newspaper "It is possible that we leave everything as it is".

Billionaire Mateschitz earlier baulked at the looming end of the customer car era, arguing that it makes no sense to bankroll two full F1 constructors.

But he now tells Salzburger Nachrichten that he is waiting for the actual rules for 2010 to be written before making a final decision.

"It will show us whether we have an interested buyer, and it could also be that we no longer want to sell," Mateschitz, 64, said.

At the same time, Gerhard Berger, the other half-owner of the Faenza based team, has been publicly and privately urging his Austrian countryman to stay on board.

And, referring to Mateschitz, the former ten-time grand prix winner told Austria's O3 radio: "He manages a fantastic balance of business sense, private life and the joy of living."
