Michael Schumacher says he is confident that the new Mercedes GP W01 is good enough to fight for the 2010 F1 title.

Schumacher makes his return this season with Mercedes after the team completed a buy-out of Brawn GP, and will be partnered by Nico Rosberg for his first year of racing since retiring from F1 at the end of the 2006 campaign.

While he admits that it is difficult to judge how the field is shaping up after the first two tests of pre-season, Schumacher insisted he was confident that Mercedes has a car to challenge for the title even if he has no experience from last year to work with.
