Ross Brawn has again re-iterated his confidence a resolution will be found with Jenson Button over his contract saga.

Brawn said he was "99% certain" Formula One's new world champion would re-sign with the team for 2010, despite an apparent disparity regarding his salary for next year.

The principal of the Brackley team said: "I see the way Jenson works with the team, the way we work with him. I think we've given him the equipment this year to show what he can do, and he knows our plans for the future. We've another little matter we've got to sort out, but I'm sure we will find a resolution, so that's why I'm reasonably confident."

Button is understood to be seeking a return to the £8m deal he enjoyed with Honda prior to their withdrawal from the sport in early December last year after taking a £5m pay-cut to drive for Brawn.

The 29-year-old, though, said yesterday that he would not wish to put any kind of percentage on his chances of staying with Brawn, adding he had been approached by other teams, albeit not naming names.

McLaren and Toyota, though, are the two teams concerned, with the rumours refusing to die down regarding a potential British 'dream team' of Hamilton and Button at McLaren from next year.

It would appear Brawn will have to find the cash from somewhere if he is to hang on to his star asset and the number one on the car as Button would take that with him should he drive for another team.

Brawn added: "I want to keep Jenson in the team, so we're working hard to find a solution to that.

"He's done a fantastic job this year, and I think he'll be even stronger in the future with this championship behind him."
