Two-time Tour de France winner Alberto Contador could retire from professional cycling in 2016.
The Spaniard, 32, has confirmed his intention to compete with the Tinkoff-Saxo team in this year's Giro d'Italia and Tour de France.
But he told a press conference: "After 2016 what I can say for now is that I don't see myself racing.
"Physically, I feel very well but it is true that the years are going by and you have to set a date," he added.
"I'd like to retire on top of a podium. This year, I will definitely be competing and also next year."
However, he broke his right tibia during the 2014 Tour de France's 10th stage, and eventually retired from the race after riding on for 20km.
Contador will start his 2015 season - the last on his current contract with Tinkoff-Saxo - on Wednesday at the Ruta del Sol, a five-day stage race in southern Spain.
He added: "I feel very good, I recover well from training, I am very excited with my team.
"While I am very well physically, I could not know exactly how many years I could compete in the grand tours. I would like to retire at the top.
"My plan is to compete at the Giro and the Tour and I don't want to be second in any of them. I just want to win both although we have to wait and see what happens."
Contador was banned by the Court of Arbitration for Sport for two years in 2012 and stripped of the 2010 Tour de France title for doping.
He was found guilty of doping after testing positive for clenbuterol during the 2010 Tour.
