Michael Schumacher says he won't compete in any other form of motorsport when he retires from F1 at the end of the season

Michael Schumacher has ruled out continuing his motorsport career in any other category when he retires from Formula 1 for the second time at the end of the season.

Having come out of retirement after three years to spearhead Mercedes' new works team in 2010, Schumacher had hoped to challenge for an eighth world title but looks set to exit the sport again without adding to his record 91 wins, with his best finish to date a third place in Valencia in June. Some pundits have suggested that the underwhelming nature of his on-track return may affect his legacy but Schumacher, despite the disappointing results, says his 'second' career has actually taught him how to accept defeat, and all in all, he's happy with his two decades in the sport as a whole. "If I look into my life's rear-view mirror, I find myself happy and smiling," he explained. "I've had two distinct careers: one where I won everything, and a second one where I discovered what losing means. "Yes, I've learned how to lose, but this has made me more mature and more patient too, partly thanks to my age. "Today I have to consider what I have done overall and I'm satisfied with myself."
