Lance Armstrong says winning an eighth Tour will not be a priority when he returns to professional cycling.
Having retired in 2005, the 37-year-old will make a return with the Astana team in January's Tour Down Under, before the Giro d'Italia and Tour de France.
"If the Tour was today I don't have the power to win, but it's months away.
"I have time to prepare. If I'm 18th or third, it's fine," he said, adding that he was unlikely to be racing for more than two years.
Armstrong, who will be two months short of turning 38 when the 2009 Tour begins, said: "It could be more than one year, it could be just one year. I don't see it being for more than two because age is a factor."
The Texan is at Astana's pre-season training camp and despite tensions earlier in the year with 2007 Tour winner Alberto Contador threatening to leave if he was not guaranteed team leadership, Armstrong said there would be no problems.
"There are some unwritten laws in cycling that say the other riders support the better rider," he said.
"Alberto is the strongest cyclist in the world. There is a chance I'm the third strongest rider in the team.
