It won't be easy for Schumacher

who, after a little over two months, feels immersed in the workings of a team where Hamilton has spent the last 12 years.

"I didn't come to McLaren not confident. I've always had confidence in my ability," insisted Button.

"I've always been pretty good at getting to grips with a new environment, so it hasn't been an issue, and I didn't think it would be."

"One thing I have always worked on is to integrate myself into a team as quickly as possible."

"As for what's going to happen this year. Neither of us know."

"We both know we're extremely quick, and you don't win the world championship unless you're quick, it doesn't matter the situation you are in."

"So it's going to be an exciting year for both of us, and we will see what happens after 19 races."
