Diego Costa's successful stint with Chelsea has had a bitter end, but his exile will shortly be over as Atletico Madrid finalised a club-record deal to buy him back from the Premier League champions. The Brazilian-born Spanish international did not return to west London this summer after being told via text message that Antonio Conte no longer had the 28-year-old forward in his plans. That short, brutal message from Conte triggered a scramble for Costa's signature but the striker, who scored 20 times in Chelsea's league-winning campaign, painted the Blues into a corner by insisting he only had eyes for Atleti.
