28-year-old Chelsea striker, Diego Costa is refusing to return to training after being told by manager Antonio Conte that he wasn’t part of his plans for the new season.
Costa is in his native Brazil after insisting he won’t return to Chelsea and only wants to join La Liga side Atletico Madrid.
Former Everton and Celtic midfielder, John Collins, has condemned Costa’s actions.
“He’s just a disgrace,” Collins told talkSPORT.
“He’s an embarrassment to the profession, to be honest, with what he’s doing and I hope he doesn’t come back to Chelsea.
“I hope they sell him because it will be a nightmare for the manager if he comes back and is hanging around the dressing room.”
