Norbert Haug has played down the latest criticisms of Michael Schumacher's performance in 2010.

Eddie Jordan, the seven time world champion's first F1 employer back in 1991, this week described the German's decision to return to the sport as a "huge personal error."

"To pitch yourself against young men 20 years younger than you is simply against the laws of physics and medicine," the Irishman told Germany's Sport Bild.

Mercedes' competition director Haug hit back: "He (Schumacher) deserves our support, he fits with our team, he still has the speed.

"We believe in him, and so do his fans," he added.

Schumacher, 41, has written off his chances of winning the current championship, but he thinks his performance hasn't been too bad in 2010.

"I'm pretty happy with myself," said the German.

"We have made a few mistakes and there are some things we can improve, but all in all ... I don't think there are many who can return after a three-year break at the age of 41," added Schumacher.
