Team Sky head coach Shane Sutton has backed rider Bradley Wiggins to win the Tour de France and become the first Briton to win the famous race.
Wiggins currently holds a lead of just over two minutes over fellow Brit Chris Froome, and Sutton believes that it will take a crash or an extraordinary performance from a rival to halt his pursuit of the win.
Sutton said: "It is going to take a good man to beat him from here.
"He has a two-minute lead, with another chance to put massive amounts of time into his opponents in a time trial, so it's looking good for him."
Saturday's 217km 13th stage sees the riders head towards the Mediterranean.
