The Chelsea striker is off contract in June and yet to agree terms over a new deal.
His agent, Marco de Marchi, told calciomercatoweb.it: "So far we have not found an agreement for the renewal, but the guy right now is under contract with Chelsea and I have not had contact with other teams.
"The boy's intention is to stay in England.
"Possible renewal? By nature I do not close the door to anyone, especially in football where the doors are often closed and then reopened."
