He only scored once again after the turn of the year, however, and has struggled for form ever since, finding himself in and out of the team under both Antonio Conte and now Maurizio Sarri.
He has been dropped from the squad entirely in five of Chelsea's last five league games; Eden Hazard has consequently been deployed in his stead, moving in from the wing to be the spearhead of attack.
Morata has spent the past few days in his Spanish homeland with the hope of completing a move away from Chelsea, but frontrunners Sevilla revealed on Monday that they are no longer in the running to sign the 26-year-old. He now earns £8million a year at Chelsea.
Sevilla's director of football Joaquin Caparros admitted on Monday that his club can not afford to offer Morata a way out of his Chelsea nightmare. He then moved to Real Madrid where he rose to prominence before enjoying spells at Juventus and Stamford Bridge.
It is claimed Atletico would need to offload one of their offensive players to allow Morata to join with either Gelson Martins and Nikola Kalinic likely to make way.
Caparros, speaking at the unveiling of another striker, Munir El Haddadi, said they pulled out of a deal due to the costs involved.
The Spanish giants have been in negotiations with his agent and Chelsea over a deal for the striker but there are still differences between the two clubs.
