How about the following for a challenge? Just ban him yourselves. Don't mention Alberto, not in any light. Positive or Negative, nor updates on the case. For the period of 2 years from which he should have been banned. Lower his stock value yourselves. If he races, just leave a blank in results rather than write his name in there. What could the UCI, or race organisations, or Alberto, or the Spanish federation, or Riis and his sponsors do about it if the cycling media were just to make it like he vanished off the face of the earth for two years?
