Bradley Wiggins confident of double victory

Great Britain's Bradley Wiggins is confident that he can win the Tour de France and Olympic gold next year.

The 31-year-old was in contention to win the Tour in 2009, but was forced to pull out after breaking his collarbone in a crash.

A number of pundits have suggested that it would be too difficult to claim victory in both events, but Wiggins believes otherwise.

"The Tour won't be there for me forever and the opportunity I have to win is so great that I can't afford to miss another year," he told BBC Sport.

"I believe I can win the Tour and Olympic gold. I want it all next year."

Wiggins has won three Olympic gold medals in his career.
