Mateschitz reconsiders selling Toro Rosso

Mateschitz - who owns 50 per cent of Toro Rosso with former grand prix driver Gerhard Berger holding the other 50 per cent - revealed his desire to sell at the beginning of the season.

But after seeing Toro Rosso's competitiveness this year, overshawdowing the Red Bull Racing team, Berger urged Mateschitz to increase his support and Mateschitz admitted this weekend that he is tempted to at least hold on to the team.

"It might happen that we leave everything as it is," he told Austrian newspaper Salzburger Nachrichten this weekend. "We haven't been informed about the new rules yet and it depends on what is written down there - which parts each team must design and produce individually.

"We will see if an interested buyer shows up, but it might happen that we do not want to sell at all any more. Right now, I would say nothing is fixed yet."

Mateschitz also confirmed that Sebastien Bourdais remains in contention for one of the seats at Toro Rosso next season, although no decision been made yet.

"We will check all the possibilities," he said. "Bourdais remains one of them, but overall, there are not that many possibilities."

He added that David Coulthard will stay on as part of the Red Bull team next season, despite retiring from racing at the end of the year.

"He will have other obligations but he will remain part of Red Bull Racing," added Mateschitz. "He will test for a couple of days and it will always be good to have his opinion. DC will be a kind of supervisor to the team."
