Diego Costa has asked Chelsea to allow him return to Spain.
Antonio Conte faces his first crisis as Chelsea boss, after star striker, Diego Costa, asked to leave the club according to AS.
Although he had been rumoured to be unsettled in London following the disappointment of last season, few expected the Spanish international leave so soon after the arrival on Conte.
Despite signing Michy Batshuayi from Marseille for a little over £33 million earlier this summer, Costa has left Chelsea looking for yet another centre forward.
Nevertheless, AS believe that Costa will not try and force an exit from Stamford Bridge, giving Chelsea some breathing space in the transfer market.
Given his previous connection with Atletico Madrid, and the fact that Diego Simeone is believed to have identified Costa as a potential transfer target, a return to the Vicente Calderón in now very likely.
