Sauber's F1 2011 rookie Sergio Perez has reiterated that he can't wait to get back racing again this coming weekend in Canada, although the 21-year-old will have to pass a fitness test this Thursday before he gets the green light to compete.

Perez had to miss the Monaco Grand Prix two weeks ago following his hefty qualifying crash on the Saturday that left him with concussion and a bruised thigh. But he is now feeling fully recovered and is raring to go again.

"I feel very good and fit. Of course I want to race in Montreal, but I also know the final decision is up to the FIA doctors," he said ahead of the latest round in the F1 2011 World Championship.

"I have never been to Montreal and know the circuit only from watching TV. Originally it was planned I would go to the Ferrari simulator at Maranello, but this had to be cancelled after my accident.

"Anyway, it is not the first unknown circuit for me and I have never had difficulties adapting. I found it very hard to be just a TV spectator for the race in Monaco, and can't wait to get into the car again."

Sauber boss Peter Sauber meanwhile is 'very optimistic' the youngster will be able to race this Sunday after encouraging tests at the weekend at a clinic in Zurich.

"The results were positive, so we are very optimistic that he will be at the start in Canada," Sauber wrote in the Swiss Sonntagsblick newspaper.

"We are hoping for a good race weekend in Canada," added Sauber technical director James Key. "Monaco was a race with ups and downs, with Kamui [Kobayashi] bringing us ten points [after finishing in P5] but with Sergio not competing after his accident in qualifying. When I spoke to him he sounded very well and was looking forward to getting back to work. We are looking forward to having him back in the car."
