Chelsea boss Di Matteo: I want Lampard to stay
The 34-year-old insisted he would "love" to stay on but there now appears to be a real prospect he could leave next summer.
Blues boss Di Matteo was coy about revealing whether he had recommended to the Chelsea board that Lampard was offered an extension but asked whether he was hopeful there would be a successful conclusion to any talks, he said: "I am, yes."
He added: "These are talks between the club and the player.
"I've been very happy with Frank and he shows his qualities that he has in every game that he plays, so a very influential player within the group as well."
