Antonio Conte is unable to guarantee if Diego Costa will remain at Chelsea next season, amid reports of interest from his former club Atletico Madrid.
Costa, who signed for Chelsea in 2014 on a five-year contract, has not featured in either of the club's preseason games on their U.S. tour so far. Speaking at a news conference after the 3-2 defeat against Real Madrid, Conte insisted this was because of injury.
Conte said: "I speak for today and today Costa is Chelsea's player. Tomorrow if you ask me if Costa will remain with us, I don't know.
"I can say that today Costa is a Chelsea player. He didn't play in these games because of injury and if he solves the injury and I see in training he's in good shape it can be possible to see him in the next game against AC Milan [on Wednesday]. But I can tell you only this."
When asked about Chelsea's interest in re-signing Romelu Lukaku from Everton, Conte chose not to elaborate.
He said: "I don't want to speak about players of other teams. This is not respectful for the club or for my players. I prefer not to speak."
