Diego Costa is reportedly hopeful that a deal can be struck between Chelsea and Atletico Madrid, one that will see him return to his former club.

Atleti are set to offer Chelsea £40m up front for the Spanish international, with a further £9m in performance related add-ons.

The player himself has flown to Madrid already as he hopes to push through a move.

As reported by Gianluca Di Marzio, Costa is in the Spanish capital where he plans to train at a private facility in an effort to force Chelsea to accept Atleti’s offer and agree to sell him.

The star striker is hoping that a deal can be agreed between the two sides, one that will allow him to train with Diego Simeone’s side until January.

He would be unable to play any games for Atleti until the transfer window opens but he would be able to train with them.

As it stands, Chelsea have been playing hardball over a deal for Costa and him flying directly to Spain is hardly going to impress the powers-that-be at Stamford Bridge.
