Diego Costa claims he was told by Antonio Conte that he is not wanted by Chelsea next season.
Costa has been linked with a move to the Chinese Super League as well as Atletico Madrid.
Chelsea would like to make a move for Romelu Lukaku.
“My relationship with the coach has been bad this season. I suppose I’ve had a bad season so I can’t go on,” Costa said.
“I’m going to be honest, the other day, Conte sent me a message saying he does not count on me for next season, so I’ll have to find a way out.
“I love living in Madrid, but I have to think about my future. It’s complicated because I cannot go four or five months without playing. I have no preference for a league, I just want to play.”
