Luis Enrique is tactically deficient. At this point to argue otherwise is to ignore the facts. He may have other strength, which may or may not have influenced the team's 5 major titles in the last 2 years, but he has two huge weaknesses that are, at this point, very evident: He is incredibly stubborn; and he is tactically deficient.
He has done a piss poor job this season with a bigger pool of players with very varied skillsets. The team is completely fractured from defense to attack by a midfield who has talent, but has no effing clue what it's playing.
You have midfielders playing out of position. AMs playing CMs. CMs playing AMs. Both playing some weird positioning very advanced up the field that only results in getting in the way of forwards, eating at their space to operate and asphyxiating their movement. Because of this you have CBs and the DM being the playmakers, the ones with the ball at their feet and their head up looking for passing lanes. I mean look at this.
That is an utter mess of a formation. Arda and Rafinha (7 and 12) practically playing on top of each other. Pique, Mascherano and Busi (3, 14 and 5) all bunched up in the center circle, very separated from the midfield.
And this is an average position. If I were to take an image of a basic Barca possession today, you would see the right midfielder on the wing to the right, the left midfielder behind the CF, and the CB duo with Busquets all alone in the center circle looking for passing lanes. Utter shambles.
Lucho better reevaluate and restructure the way he has this midfield playing or this league season could be very well lost in the next two La Liga games.
