Michael Schumacher is confident that he can challenge for the world title this season following his return to Formula One as part of the new-look Mercedes team.

The seven-time world champion has ended his three-year retirement to drive for the team which raced under the Brawn GP flag last season.

Jenson Button won the championship driving for them last year and Schumacher is optimistic about his own chances of success in 2010.

Speaking at the official team launch, the 41-year-old German said: "I have to say that I am totally committed to this new challenge.

"This season feels like a re-start for me and I am so motivated. We have a very exciting combination at Mercedes GP Petronas.

"I am convinced that Mercedes will be in a very good position to fight for the championships this season and I will definitely give it a go.

"Driving for Mercedes-Benz again is like the closing of a circle for me as I started my racing driver career with the three-pointed star on my helmet.

"This is another reason why I cannot wait for the competition to get underway."
