Didier Drogba has refused to rule out the possibility of staying with Chelsea when his contract ends in the summer.

The striker is wanted by MLS side Chicago Fire after he rejected a move to Chinese Super League side Shanghai Shenhua in January.

The 33-year-old has made just 13 starts for the Blues this season, scoring six goals, and is competing with Fernando Torres, Daniel Sturridge and Juan Mata for a place in attack.

He is currently involved with the Ivory Coast squad in the Africa Cup of Nations and is preparing for the knock-out stages of the competition.

Speculation will once again persist over his future when he returns to the Premier League, but Drogba admits his options are open.

He said: "I am a free agent at the moment, so I can talk to any club unless I sign a new contract with Chelsea.

"My doors are still open to Chelsea, no doors are closed.

"I am just thinking about the African Nations Cup, which I want to win with my team-mates for the Ivorian people."

Meanwhile, Chicago Fire coach Frank Klopas has confirmed his interest in Drogba and is hopeful of agreeing a deal.

He said: "We are very interested in Drogba. We're having talks at the moment, but we do not know if he will come or not."
