Chelsea will hold talks with Diego Costain what promises to be a frantic summer after the striker issued the club with an ultimatum over his future.

Just hours after Chelsea missed out on the Double by losing the FA Cup final to Arsenal, Costa insisted that he would not be pushed to China and Atlético Madrid were the only club he was interested in joining if he left.

Costa claimed he was happy to stay at Stamford Bridge, but contradicted himself by saying he would have to leave if the club signed a new big-money striker. That is unlikely to deter Chelsea in their pursuit of Romelu Lukaku.

Costa’s situation is the most delicate facing the club this summer, but as many as nine of the first-team squad who won the Premier League title have doubts over their futures.

John Terry and Asmir Begovic, who will join Bournemouth, are definitely on their way out, while there is uncertainty over Nemanja Matic, Cesc Fàbregas, Michy Batshuayi, Nathan Aké, Kurt Zouma, Ruben Loftus-Cheek, Kenedy and Ola Aina.
