BERLIN — The head of cycling's world governing body has welcomed Lance Armstrong's return to the sport but doubts he can win an eighth Tour de France.

"The comeback is excellent for the sport," Pat McQuaid said Friday in Berlin, where he attended a six-day race.

"There were only positive stories about Lance on Monday," McQuaid said of Armstrong's start at the Tour Down Under in Australia.

Speaking of Armstrong's prospects for an eighth Tour de France winner this year, McQuaid said he did not believe the 37-year-old Austin cycling great would extend his record of seven wins.

"He will lead (Astana teammate) Alberto Contador to victory and finally win the hearts of the French," McQuaid said.
