Spanish striker, Diego Costa is yet to return to Chelsea after his summer break, as it appears he has no future at Stamford Bridge.
Costa even posted a video of himself partying in Atletico colours Jersey while mocking Conte.
The 28-year-old, who was told by Antonio Conte he was not in his plans for the coming season, is eyeing a return to former club, Atletico Madrid.
With his teammates in Singapore, Costa has decided to get to work with some drills on the beach.
The striker was tied to a harness as he completed some basic volleying exercises.
He uploaded a clip to Instagram as he was put through his pace by two assistants.
Costa remains in midpoint over a potential transfer, with Atletico under a transfer ban until early next year.
A loan move to China or AC Milan was mooted but that now appears unlikely.
Costa can sign for his former club this summer but will not play until 2018.
