Lance Armstrong vs. Alberto Contador
When Lance Armstrong returned from retirement to compete in the 2009 Tour de France, he explained he only wanted to be a part of a team, and went so far as to rejoin Astana without a salary. Three stages into the Tour, however, it was a different story. Armstrong began to argue with 2007 Tour winner Alberto Contador and dueled for the spotlight with his so-called teammate. After winning the Tour, Contador told the press he appreciates Armstrong's athletic skill, but will never admire him on a personal level.
