Michael Schumacher believes Mercedes GP will be fighting for the title this season.
Schumacher finished last week’s Jerez test as the eight fastest driver and he feels the car has shown enough potential to allow him to fight for both driver and constructor honours.
"I am fully convinced that we have a car that is able to fight for the championship," Schumacher told the official Formula One website.
"Where we are exactly is hard to say. This is especially true for me as I don't have the data from last year's car."
Schumacher said he was now full prepared to race again and feels recharged after his three-year sabbatical from the sport.
“To drive a car like this again, it was just that great old feeling I know so well," he said. "Nothing comes close. I love that sensation, I always did. It was just that my batteries were empty at the end of 2006 that I retired.
