Portsmouth midfielder Lassana Diarra won't rule out a return to former club Chelsea.

He told the Sunday Times: "We have good players here, and though the objectives are different from Arsenal and Chelsea, we will try to go into Europe and do something good. It's not a problem for me. Maybe one day I will go back to a team like Chelsea, but I don't want to think about that. They make me very comfortable here, so I will never forget this."
