No more of this "no comment", this time we get a proper answer from Contador.
"Q: Can you tell us you’ve won clean and can you make a strong stand against doping?
AC: Like I’ve said, I am available 365 days to doping control. I am never with an excuse. I am always in favor of the anti-doping controls. It’s good for the sport, for cycling, which I love so much. I always pass the controls with a happy face and I will keep undergoing them. "
