Radamel Falcao has thrown fuel on to the transfer fire after admitting he is planning new challenges in the near future.
The Colombian striker has been a long-term transfer target for Chelsea, but put an end to speculation in the summer after agreeing a move to French club Monaco.
But rumours of discontent have alerted Jose Mourinho that Falcao may be available in the January transfer window.
With Chelsea in dire need of a talismanic striker, Mourinho was thought to be considering a £60m bid for the Colombian international.
Monaco officials have so far dismissed the chance of Falcao leaving the principality club in January, but Falcao may have other ideas.
Speaking with Colombian newspaper El Tiempo, Falcao admitted that he is not planning on staying at Monaco for the rest of his career and is planning a new challenge already.
Speaking of his future, he said: "There will be new challenges and new goals.
"I don't want to stop, I want my ambitions to grow and will continue to work hard every day to become stronger."
Falcao has had a mixed time in Ligue 1 so far, scoring nine goals in 14 games, making him fifth in the race for the Golden Boot behind the likes of Edinson Canvani and Zlatan Ibrahimovic.
