Chelsea and Atletico Madrid have reportedly opened talks regarding a possible swap deal involving Filipe Luis and Koke.

The Express reports that the Blues are ready to send Brazilian left-back Luis back to the Vicente Calderon but are eager to lure Koke to Stamford Bridge.

23-year old midfielder Koke signed a five-year deal with los Rojiblancos last year, which includes a release clause of £44million, while Luis is valued at around £14m.

It is believed that newly-crowned English champions Chelsea are prepared to part with £30m and Filipe in order to land 16-time Spain international Koke.
