Bourdais: Vettel move 'good and bad'.

Sebastien Bourdais has admitted that he views team-mate Sebastian Vettel's move to Red Bull Racing for the 2009 Formula One season as both a good and bad thing for his own F1 future.

With David Coulthard having announced that he would retire from F1 at the end of the season, it was viewed as a case of when, not if, Vettel would be named as his replacement, with Red Bull duly confirming that the young German would join Mark Webber in its line-up for 2009 on the eve of the Hockenheim race weekend.

Speaking about the move, Bourdais admitted that it could be a good thing to see Vettel move on to pastures new, although he added that it could also be a negative if that becomes the reason why he retains his own seat with the Toro Rosso squad for 2009.

"It's mostly a good thing for me because the team will probably not want to change both its drivers at once," the multiple Champ Car title winner was quoted as telling French news agency AFP. "[However], if they keep me because they don't want to change their two drivers at the same time, that's not very exciting either.

"I'm not questioning myself in regards to next year."

Although he has seen the flag in four of the five races since the new Toro Rosso STR3 was introduced in Monaco, Bourdais stated that he still didn't feel as comfortable as he did in the old car, with the Frenchman having struggled to get to grips with the car as quickly as Vettel - who has scored on three occasions since the car debuted in the principality.

"I just want things to work as they did with the old car even if its performances were not as high," Bourdais admitted. "I've found a little something in regards to braking. It's rather positive, but that's only one problem solved in three..."
