Button predicts Hungarian thriller

Button would not be drawn to comment on contractual disputes, however, saying: "There has been a lot of speculation in the press. Both parties have said a lot, maybe too much, and that's it for now."

Widely regarded as one of the paddock's more human figures, however, Button admits that Hungary will be a tough weekend for him.

"It won't be the easiest weekend of my life," he conceded, "But I've got a job to do here in Hungary and I'm very much looking forward to this weekend.

"The car is going to work very well here and the team is very positive, like I am. I'm going to give 100 percent as I always do and hopefully we are looking at another good race like Hockenheim, but starting a bit further up the grid.

"We want to do the best we can. That's my view and the team has the same view. It will be so competitive here, more than any other race. The Renaults will be strong like they were last year and the McLarens have also been strong over the last few races. It should be very exciting."
