The Team Sky boss Sir Dave Brailsford believes Tour de France winner Chris Froome can be a multiple champion.
Froome, who won his first yellow jersey yesterday, says he'd like to contend for the next five years.
Brailsford says he has the physical and mental attributes to be competitive in this race, if nothing drastic changes, for quite some time.
He says Froome isn't at his best yet, he can still reach a better physical condition than he is in now.
Brailsford has delivered back-to-back Tour de France champions after Sir Bradley Wiggins became Britain's first winner of the event last year.
