Tour de France winner Alberto Contador has launched a stinging attack on teammate Lance Armstrong, saying relations between the two were tense throughout the race.
The Spaniard says his relationship with Armstrong is non-existent.
Contador says even if he is a great champion, he's never had admiration for him and he never will.
Contador won the Tour yesterday with a comfortable lead over his rivals.
His Astana teammate Armstrong, a seven-time Tour de France champion who came out of retirement for the 2009 event, came third.
