Chelsea striker Diego Costa has told Atletico Madrid that he is ready to make a comeback, Sky Sports has claimed.
The Spain international will leave Stamford Bridge in the summer after his relationship with manager Antonio Conte came to an abrupt end.
The Italian has made it clear that there is no space in his squad for the striker.
Reports in Italy have claimed that the two clubs will reach an agreement for £50million.
Following Spain's 2-2 draw with Colombia at the beginning of the month, Costa said: "I'm a Chelsea player, but they do not want me there.
"Antonio Conte has told me by message that I do not follow at Chelsea and that's it. Conte said he did not count on me for next season.
"It's a shame, I've already forwarded the message to Chelsea people to decide. But it is clear that the coach does not count on me and does not want me there."
