Humble Armstrong ready to work for Contador

VERBIER, Switzerland: Alberto Contador is the best rider in the world and showed on Sunday he has what it takes to win this year's Tour de France, his teammate and great rival Lance Armstrong said.

"Now you know who's the best rider in the world and the best rider in the race. In the past I was the best, now he's the best," he told journalists after the Spaniard's takeover in the Tour 15th stage in Verbier on Sunday.

Since Armstrong retired after a record seventh Tour victory four years ago, Contador had been peerless in big Tours, winning the Tour in 2007, the Giro d'Italia and the Spanish Vuelta in 2008.
