Spain striker Diego Costa claimed he was coming home after completing his return to Atletico Madrid from Chelsea on Tuesday.

Both clubs finally reached an agreement for a reported initial €55 million on Thursday and the Brazilian-born striker has now completed his medical with the Spanish giants.

"I’m very happy to return home, I’ve always said it, Atletico is my home, I’m very, very happy," he told the club's website.

Costa can't feature until January as his move was completed outside the transfer window.

However, Atletico said he will begin training immediately and is likely to be in the stands when Chelsea are the visitors for the first ever Champions League game at Atletico's new Wanda Metropolitano on Wednesday
