Barcelona will reportedly offer Cristian Tello to Atletico Madrid in order to secure the signing of highly-rated Spain midfielder Koke.
Koke, 22, is widely regarded as one of the best central midfielders in European football, with his form last season helping Atletico win their first La Liga title since 1996.
The Catalan outfit have long been linked with a move, but thus far Atletico have repelled the interest.
According to Sport, however, Barcelona are prepared to offer Atletico Tello in addition to a significant transfer figure in order to secure his services.
Koke is currently with the Spain squad at the World Cup.
