Button tries to psyche out Webber

Last season Button was in Webber's current position, going into the final races trying to defend a lead. So he knows how to play the mind games that were used on him a year ago. Webber has not won a race since the first week in August, and is well aware of this fact.

"Mark is pretty strong in the head," Button said. "Everybody plays mind games, though. I travelled over with Mark and it was fun - because I have been in his position. It's the little things like me saying: 'Are you feeling the pressure, mate?' You always get a reaction, even if they say: 'No, I'm not.'
