Former world champion Niki Lauda does not believe Michael Schumacher will make a full-time return to Formula One next season.
Speculation has linked Schumacher with a return to the sport he once dominated following Mercedes' takeover of Brawn GP earlier this month. But Lauda said: "I don't believe there is one single grain of truth in it, at least from all the signals I get. There was a window of opportunity after Felipe Massa's accident and, had Michael been fit, he would have taken up that chance to race for three or four races. But I cannot believe he would be up for a full season."
