Robert Kubica returned to the Circuit Gilles Villeneuve a year after his horrific crash at the Canadian Grand Prix.

The BMW Sauber driver, currently fourth in the drivers' world championship, escaped with just a concussion and a sprained ankle following a high-speed crash early in last year's race.

Kubica said: "Canada is one of my favourite tracks. Of course everybody knows what happened in 2007, but I don't have to cope because it's already a year ago, and since then I have been driving a Formula One car without thinking about it."

He added: "In Formula One and motorsport, the risks are high. But I don't have any negative feelings about Canada. I am just coming here as I go to any other race, with the goal to score as many points as possible."
