Midfielders

Barcelona's midfield should ideally be: Defensive Midfielder - Sergio Busquets, Left Attacking Midfielder - Phillipe Coutinho, Right Attacking Midfielder - Arthur.
Barcelona have had their golden days with Busquets, Xavi Hernandez and Andres Iniesta bossing their midfield. This midfield has been Barcelona's trademark for many years. However, Barcelona's main problem now is in that area.
They are so predictable in midfield and the players lack the creativity to break the opposition lines. Because of that, Messi constantly drops deep to organise their play.
Coutinho usually plays on the left wing. He is useless on this position and Valverde should drop him deeper in the midfield and play him as a No.8. This position is very similar to him because he has played there under the guidance of Jurgen Klopp.
Also, Coutinho's playing style is very similar to Iniesta's and he could play his role very well. The Brazilian wonder kid, Arthur should play from the start. He is a very good player with great passing skills and most importantly he is very press resistant. Many fans think that Arthur is the successor of Xavi. Busquets should be there to protect their back. Simply, this squad is unimaginable without him.
