Chelsea being tempted by a second colossal City bid for their skipper, Hiddink said: "I'm not in a position to think about that but what was stated very clearly, by the club and by John himself, who made a very clear statement, is that he is a Chelsea man.
"I'm not the money man here but he made it very clear, and the club made it very clear, that they want to continue forever.
"There are some players who are brought up within this club and it is difficult to sell them. For the economical part you need to speak to the CEO, but there is a kind of history with him - his statement was clear and the club's statement was clear also.
