London - German Formula One star Timo Glock has no doubt that compatriot Michael Schumacher will return to the track in time for the 2010 season.
Schumacher retired three years ago but speculation is rife about a comeback with Mercedes GP and Glock, who will be driving for the newly-formed Virgin Racing next year, is convinced there is more to the story than rumour.
"There's still a lot of speculation, but in the end he is a crazy race driver, and he wants to come back to racing," said Glock.
"It's not enough for him to just do go-kart races, or go to the Race of Champions at the end of the year.
"The flame is still there, it's still burning within him, and it will be great for Formula One if he comes back.
"For me, my personal feeling, it is quite obvious he is coming back.
"For Formula One and the fans it would be a big boost, a seven-time world champion coming back after three years out.
"It would be a mega highlight, and to drive for Mercedes, you would have a German driver in a German car."
