Barcelona boss Luis Enrique has reportedly made Atletico Madrid midfielder Koke his next major transfer target.

Despite being just 23 years of age, Koke is already regarded as one of the best midfielders in European football and is now seen as a key player for Spain.

Koke's performances last season helped Atletico win their first La Liga title since 1996 and the final of the Champions League last season.

According to Sport, Enrique has asked the club to target the Spaniard, who has a £44m buy-out clause in his current contract.

Barcelona cannot officially sign any new players until January 2016 due to their transfer ban, but it is understood that deals can be agreed this summer.

Koke helped Spain record a 1-0 win over Ukraine in their Euro 2016 Group C qualifier in Seville on Friday evening.
