Robert Kubica says some of the doubts upon his F1 return hurt him following serious injury, but his Le Mans win in a Ferrari proves many wrong.

Kubica's big break with Ferrari's Formula 1 team fell apart after a devastating injury. On Sunday, he was the reason Ferrari won Le Mans race overall.

But on his fifth trip to Le Mans, Kubica took overall victory during the same weekend when F1 hosted its Canadian race – the site of the Pole’s sole grand prix win, which came in 2008 and briefly took him to the top of the drivers’ standings.
