Michael Schumacher insists he is still driven to succeed in Formula One despite uncertainty over his future For Schumacher, six years after retiring first time around, the exit is looming again, although there are rumours he could yet replace Sergio Perez at Sauber after the Mexican's switch to McLaren, whilst an 'upstairs' role at Mercedes is also a possibility. Then there are the fans: they love motor racing and it is fun to feel their passion. Logically, it would also be nice to achieve a sporting highlight this weekend, although my chances are of course very limited because of my grid penalty. But I've always approached these things as a challenge.
