But he says his long-term future is at Chelsea, as long as club owner Roman Abramovich is keen for him to stay beyond his four-year contract.
"I want to think about the contract I have now, which is a four-year contract - and I have three and a half years left," he said.

Mourinho's side have scored the fewest goals among the Premier League's top four and his strikers have only contributed 20% of Chelsea's goals this season - the lowest by any strikers in the Premier League.

"I don't need a new contract. I don't need more money because I get enough and the club knows because I told them, 'I stay until you want', so when one day Mr Abramovich decides that I am not the man, he tells me and I go.
"But if in three years' time, he says they want me to sign a new contract, then I sign a new contract because I don't want to leave. Simple as that."
