Button expects show of Brawn

The man regarded as a technical genius was appointed by Honda as team principal three weeks ago, ending his year-long sabbatical from Formula One where he won six consecutive constructors' titles and five successive drivers' championship with Ferrari and Michael Schumacher.

"Everyone knows what Ross has achieved in the past," said Button. "Before he even opens his mouth, he lifts people because of what he has achieved. He comes with a lot of experience and he falls into a role we have not had for a long time, which is leadership on the technical side."

And while Button is not expecting Honda to challenge the might of the Ferraris and McLarens in 2008, he is still expecting significant progress.

"Ross will make a difference, but it's not just down to one man. We can't just hope Ross can make the big difference, we have to think about other people," he continued.

"Aerodynamically we have had to work hard, and we've employed some good people who have given those who have been at the team a long time some good, fresh ideas.

"I think we've made a massive difference - and I'm not talking about the car, I'm talking about the personnel - so the future is looking very exciting for Honda."

Button did, however, warn that expectations should be kept in check.

He added: "Next year is going to be a good year, although I don't think you can say we're going to be challenging for the championship because we won't be strong enough at the first race," he said.

"Coming from where we were to winning the world championship has never been done before. So we are pushing hard for a good car, and for me the most important thing is to see improvements every race we go to next season."
