Mar.4 (GMM) Reigning GP2 champion Timo Glock has played down his chances of setting the formula one world alight with his Toyota in 2008.

The German has pulled off the rare feat of resurrecting his grand prix career following an abortive debut with Jordan in 2004.

But having being named to replace Ralf Schumacher this season, and at the end of a long winter period for Toyota, Glock has delivered a sobre message with just 11 days until the Australian grand prix.

"I have not managed to adapt the car to my driving style, and the speed has suffered," he said after the final test in Barcelona recently, according to the Cologne newspaper Express.

Glock, 24, is also in two minds about the consistency of Toyota's new single seater, the TF108.

Referring to the Barcelona test, he said: "It was strange that our speed on Monday morning was okay, and from then on we went down."
