#5 Koke (Atletico Madrid)
The Atletico Madrid youth academy product is one of the best midfielders in La Liga. He is a proven winner as well, winning 2 Europa League's, 1 La Liga, 1 Copa del Rey and 1 Supercopa de España.
Not only attacking wise defensively as well he contributes a lot to the Atletico Madrid team that play highly defensive football. The Spaniard is one of the most hardworking members of this robust Atletico team.
FC Barcelona also has a good relationship when it comes to transfers with the red half of Madrid. In recent seasons Los Rojiblancos have been a constant threat to Barca's league dominance and his signing could prove to the decisive blow that will help them cement their domestic dominance even more.
Like most of the Spaniards, he is technically and tactically excellent. He also provides good physicality as well. Though it is Lionel Messi who runs the show at Camp Nou, they also need someone like Koke to provide them with physicality and that graft in midfield.
Paulinho is a player who provides them with stoutness, but he has been inconsistent in his first season. Thus Koke would be a wonderful addition to the Catalan giants squad, adding depth as well as quality.
Though it will be very tough to prize him away from the Wanda Metropolitano, but in football, nothing can be taken for certain. If he does move to the Camp Nou it will be a good buy for the Catalan giants.
