Chelsea have agreed a £32m deal with Atletico Madrid for striker Diego Costa, according to Sky sources.

Costa, who has played a starring role in the Spanish club's run towards a possible La Liga/Champions League double, has long been linked with a move to London, with Jose Mourinho desperate to sign a prolific striker.

Mourinho suggested at the end of Chelsea's final Premier League game of the season that he was keen to make his biggest splash into the summer transfer market as soon as possible.

The deal with Costa is not expected to be formally announced until early June, after the big two games he is fighting to be fit for.
