Button does not fear win run ending

The Briton is chasing his fourth straight victory at this weekend's Turkish Grand Prix and, although beaten to pole position by Red Bull Racing's Sebastian Vettel, he thinks it is the challenge from team-mate Rubens Barrichello that is more likely to cause problems soon.

But, even if Barrichello starts delivering some strong results, Button thinks he will be able to cope with any heartbreak.

"In every race your team-mate is the key person to show if you're doing a good job or not," he explained. "Every race I know I have got a very competitive team-mate.

"If I don't win here it will be a strange feeling. And because we've had so many highs this season, controlling that feeling - because 100 per cent it's going to happen sometime - of not winning a race is something I will have to deal with. That maybe is when you start thinking about the bigger picture."

Barrichello said in the build-up to the Turkish Grand Prix that he was confident he would end his victory drought soon - especially since changes to the team's braking system have helped get him more comfortable in the car.

And on the back of that situation, Button thinks that there is no way he will maintain his position as Brawn's only victor this season.

"Averages say so and I have a very quick team-mate," he said. "It's not as if I've got a newcomer or a guy that doesn't know how to win races. He's very competitive.

"Michael [Schumacher] had this situation with Rubens when Rubens was allowed to race him. He was very, very quick. I can't forget I've got a team-mate who is going to push me very hard and he has this year, especially the last couple of races.

"The package of the car has suited him a little more than the package at the start of the year. He was suffering with his brakes and he isn't any more. That puts pressure on us both but I think that's a good thing."

And Button has also admitted that life at the front brings with it far more stress than comes from being stuck at the back of the field.

"Michael won seven world championships. I can understand why that guy retired. I'm sure it was the most stressful time of his life.

"It sounds stupid that being at the front with so much to play is more stressful than being further back on the grid. I've been in both situations and I know."
