Atlético Madrid and Chelsea have reached an agreement for the transfer of Diego Costa, according to Radio Estadio, a programme on the Spanish station, Onda Cero. The report states that the rojiblancos will pay 45 million euros with a potential further 10 million euros in add ons to return the Spanish international to their ranks, although there are still issues between the player and the London club.

Costa and Chelsea dispute to be resolved

Atlético will not pay the transfer value until both Costa and Chelsea have resolved their differences. The player has so far refused to return from Brazil to train with the Stamford Bridge squad, basing it on "a lack of respect" shown to him putting him with the youth team. For his no-show he has already accumulated 300,000 GBP in fines and Atleti will await the resolution to this dispute first.

Atlético playing return on hold for Costa

Costa has reiterated his desire to return to the Spanish capital, despite knowing that he would not be able to play for the team until January due to the player registration sanctions placed on the club. Assuming this transfer goes ahead, Atleti will pay seven million euros more than the price they sold him to Chelsea in 2014, the value of his 38 million euro buy-out clause. Previously the amount being asked seemed to be beyond the spending of Atlético.
