Mark Cavendish backs Team Sky's dual Tour aim

Mark Cavendish is adamant that Team Sky can support his attempts to defend his sprinters' green jersey in the Tour de France as well as backing fellow British rider Bradley Wiggins' target of winning the race overall.

World champion Cavendish also tells BBC Sport's Matt Slater that the flatter route for the 2012 Tour will benefit his attempt to win gold in the London Olympics road race which happens six days after the final stage of the Tour.
