Things have really gone from bad to worse for Diego Costa.

The striker has not played for Chelsea since the FA Cup final in May, following which he claims manager Antonio Conte sent him a text, telling him he was not in his plans for the new season.

He is seeking a move back to Spain in the transfer window.

Costa was interviewed at home in Brazil on the same day Chelsea lost their opening Premier League game against Burnley and said he was refusing the club’s demand to return to play with the reserves.

“They want me to be there training with the reserves. I wouldn’t be allowed access to the first-team dressing room and I would have no contact at all with the guys.

“I’m not a criminal! I don’t think it is fair after all I have done to be treated like that.”

The Brazilian-born Spain international, who joined Chelsea from Atletico Madrid in 2014, said if the club did not allow him to move before the transfer window he was prepared to see out his contract unpaid in Brazil.

The situation is complicated by the fact that Atletico is currently banned from signing players in this window although a loan deal would be possible.
