Mourinho lashed back to Roberto Martinez on his Criticism

Jose Mourinho has hit back at Roberto Martinez's criticism of Chelsea's pursuit of Everton defender John Stones.

Rumors have it that Premier League champions are set to table a bid of £28 million with their initial £20m rejected, but Martinez has shown that he's unhappy at Chelsea's "open" pursuit of the 21-year-old.

Roberto Martinez has condemned Chelsea's public chase for the English defender, with the Blues boss joking that he will now only bid when the transfer window is shut

Mourinho has insisted that unless he is told the player is not for sale, he will improve the club's bid saying that "it's an open market", and now joked that he will only bid in Martinez's "strange world" when the window shuts.

"Our strategy for the Premier League is going to change next year," Mourinho told reporters. "Next year we are going to make the first bid on the 1st of September.

"On the 1st of September we will do a bid for the season later. Because at this moment, until the 31st of August, it is closed. The market is closed. We are all in a strange world. We are all in a strange world.

"We think it is open but it is not open. It is closed. So on the 1st of September we are going to make a bid for the next season."

The expected bid for £28 million is in excess to the £3m Everton paid to acquire stones from Barnsley two years ago.

He added: "That is the market. And you only pay it if you want. If you don't want to pay it, don't pay. It's as simple as that. The market has no rules or limits from season to season.

"And the only surprise comes that the limits change – and not even the introduction of [Financial Fair Play] is able to control the market. The market is where it is and it's up to the clubs to decide yes or no."
