Diego Costa’s Chelsea career is effectively overafter Antonio Conte made it clear there will be no U-turn on the striker’s future as the club battle to get a deal for midfielder Tiemoue Bakayoko over the line.

Chelsea are aiming to complete the signing of Bakayoko from Monaco this week, despite problems emerging over the £35 million transfer that the club thought they had clinched a fortnight ago.

Bakayoko’s move has been held up by a knee injury after he underwent surgery at the end of last season, which has prevented him completing a medical.

Chelsea hope they will be able to complete the medical over the next few days, but Monaco have also been angered by the proposed payment schedule and the Premier League champions’ refusal to pay closer to £40m for the 22-year-old.

Monaco have claimed that Chelsea’s stance could allow Manchester United to hijack the Bakayoko deal, but sources have also told Telegraph Sport that Nemanja Matic still hopes to join the Old Trafford club.
