Yates and Indurain backing Froome and Contador in the Vuelta

Chris Froome and Alberto Contador are widely rated as the top two favourites for the Vuelta a España, but according to Team Sky sporting director Sean Yates, who knows both riders well - he directed Froome to second overall in the Tour behind team-mate Bradley Wiggins, and also Contador when he won the 2008 Giro - when it comes to trying to beat the Spaniard, it will be as much about teamwork by Sky as it will be about Froome himself.
