Hamburg - Seven-time Tour de France winner Lance Armstrong may have to support his Astana team-mate Alberto Contador in next year's Tour, the team's cycling director Johan Bruyneel said.
"At the end of the day, the strongest rider will be supported, regardless of that person's name or what they've accomplished in the past," Bruyneel said on the team's website.
Contador won the 2007 Tour de France and followed that up by winning this year's Giro in Italy and Vuelta in Spain.
"Alberto is the best professional cyclist in the world," Bruyneel said. "The strongest rider will be supported."
Armstrong, 37, announced last month he was coming out of retirement to ride with the Astana team in 2009.
