Mental strength is also a factor in all of this. Reading
@mou's recent tweets with the article about psychological training is something Pogi is also working on in his arsenal. I never had contador as being particularly strong mentally, in fact it might be his worst skill set. And it shows in his doubts while appropriating Pogi's situation from his perspective. Tell yourself you can't do something and what you visualize is what you become. This is exactly what happened to Remco at LBL in my opinion.
