Geraint Thomas has hinted that he is willing to leave Team Sky and says he will listen to offers from other teams.
The Welshman's contract with Team Sky is set to expire at the end of 2018 and he has been linked with several other teams already.
Thomas was involved in the Giro d'Italia earlier this year -his first Grand Tour as Team Sky's leader - but he will miss the race in 2018 as Chris Froome has decided to take part in it.
"This year my programme is based on what Froomey's doing," said Thomas. "I'm certainly going to listen to some teams.
"Trek-Segafredo have shown an interest and there are some other teams as well. I certainly want to sit down and listen to what they've got to say.
"I'm not getting any younger. I don't feel old, but I'm 31 now and I probably only have three or four more years at the very top, so I want to make the most of those.
"I'm not saying I want to leave or I'm going to but I certainly want to sit down and see what everyone has got to say."
Thomas has been with Team Sky since 2010 and has enjoyed some success in the last seven years, winning notable stage races such as Paris-Nice and the Tour of the Alps.
Thomas suffered a broken collarbone in the Tour de France in July and is 1/66 to win the race in 2018 while Froome can be backed at 100/1.
"Obviously Froomey will still be the leader going into it but it might be more of a chance for me to have more of a go myself," Thomas added.
"The Vuelta after that could be a potential race for me to go into in the full team leader role."
