The Spanish cyclist Alberto Contador says he will quit the Astana cycling team if his leadership is put in doubt by the arrival of seven-time Tour de France champion Lance Armstrong.
Armstrong announced he was joining Astana, reuniting him with his friend Johan Bruyneel after three years in retirement.
Now Astana's team director, Bruyneel coached Armstrong during his Tour victories.
Contador, winner of the 2007 Tour de France, says he received offers to sign with other cycling teams, though he is not considering them right now.
He says however, if he's not happy he will change teams.
Armstrong was an inspirational figure for Contador while the Spaniard was recovering form a massive blood clot in his brain in 2004.
