The Premier League champions have rejected an opening bid from the Blues for the striker and insist he is not for sale, with the two clubs at odds over whether players were involved in the bid.

"I think that this situation is clear - nothing is a secret anymore," he told reporters.
"What we did, we did officially, in a clean way. There is nothing more to say and nothing more to do.
"We want the player. We made the bid and now we have nothing more to say.
"Now we have to respect Manchester United and be ethical in this process so no more comments.
"From now on I don't say one more word about Wayne Rooney because we all know we want him. It's up to Manchester United and up to the player.
The Chelsea boss was then asked if the club had made other bids, to which Mourinho replied: "No, and we won't."
He was then asked whether it is now "Rooney or bust", replying: "yes."
Early reports suggested Chelsea had offered Juan Mata or David Luiz in exchange for Rooney, with the Europa League winners later denying those claims, and Mourinho backed up the club's stance.
"No players are involved, no David [Luiz], no [Juan] Mata and no possibility of a player involved in our bid," the Portuguese boss added.
"We don't want to make public what has to be private which is the official bid we made.
"The official bid is about a certain amount of money, it doesn't involve players and doesn't involve players in the possibility of the negotiations continuing."
Rooney's future at Old Trafford has been up in the air since Sir Alex Ferguson revealed he had asked to leave the club, while Mourinho had previously implored the wantaway striker to "do what makes him happy".
