Team Sky will be looking to deliver a fourth Tour de France title for Chris Froome, leader of their riders, as the race starts today.

His most obvious obstacle will be Richie Porte, BMC Racing’s lightning Australian. But Porte’s sheen was dulled after he was beaten by Jakob Fuglsang on the final day of the Critérium du Dauphiné.

Will that play on Porte’s mind, giving Froome the edge to win this for a third consecutive year?
