Mario Quintana has admitted that he has changed nothing to combat the threat of Chris Froome in the final week of the race.
In last year's race, Froome got stronger and stronger and the Team Sky rider went on to win the race for a second time.
Quintana said at the Movistar press conference in Saint Lo: "No, I have changed my plans at all but I have done lots of preparation.
" I think the third week will be tough."
