Kirchen talks about the Schleck brothers:

I've found an interview with Kirchen on VeloNews in which he talks about his relationship with the Schleck brothers.Here what he says:

J: There was a lot of talks in the media about the Schleck brothers and you.How do you get along?
Kirchen: We come from the same country and we're teammates on the national team.The relationship was very good before.We have different thoughts about training and tactics.Everyone has their own ideas.We are 3 good riders from the same small nation and we're very motivated to get good results.There's a rivalry between us,and that's healthy because it shows that we're coming up strong.We're happy to have this now,3 big riders from Luxembourg.It's Ok.We aren't best friends,we're not at war,but we talk to each other.We're responsible.
J: Suddenly Luxembourg is at the top of the peloton,with you and the Schleck brothers.
KK: For a nation of only 500 000,it's very special for Luxembourg.We're a small nation,so it's important to get victories and to wear the yellow jersey.We all race hard for the national team.We're proud.Cycling is really coming back again.The "problems" between the Schlecks and Kirchen began at last year's Tour,when CSC tried to put Kirchen (that was wearing the yellow jersey) into troubles during a stage (that's what Kirchen said).Before of last July the Schlecks and Kirchen were close friends (or at least it seemed.Frank even went to Kim's wedding!),then things changed.There's an old video with Frank about what happened in the Tour on this link http://www.youtube.com/watch?v=hGzM90eWdvU .The "interesting part" (or at least the one in which they start to talk English) is from 1.49 to the end.Other articles on these links http://www.velonews.com/article/79890 (it's with KK) and http://tour-de-france.velonews.com/article/79963/frank-schleck-says-he-s-happy-to-see-kirchen-in-yellow (there's also a video with Frank that my computer refuses to show me...Hope your computers are better than mine!).
