Chelsea manager Rafael Benitez has refused to confirm if Frank Lampard will still be with the club after the January transfer window.
The England international's current contract is due to expire in the summer and talks over an extension are believed to have stalled.
As a result the 34-year-old has been linked with a host of clubs, including Queens Park Rangers and Los Angeles Galaxy.
When asked about his midfielder's future, Benitez said: "The future of players is always the same. I can't say too much. He is fully committed in every training session and every game.
"He is an important player for us but I can't say too much about how he feels [regarding his future]. I'm happy with his attitude."
Lampard joined the Blues in the summer of 2001 from West Ham United.
