I don't understand why he has abandoned this system with Messi as a false nine, Dembele RW, and Suarez in a LW/striker hybrid role. Going back to this system would solve so many of our problems.
Currently we play with Coutinho and Messi in the offensive half spaces where they often drop deep to initiate attacks.
This creates several problems:
1. First of all the overall structure of the team is bad. Our Midfielders are instructed to stay deep. Often they stay in a flat line of three. There is not enough diagonality to create connections to the forwards. There is a lack of presence in higher positions.
2. Lack of depth. Suarez is often the only player that pins the opposing defenders back. This means that the opponents defenders can step out without getting exposed.
3. Abandoned right side. With Messi moving inside and Sergi Roberto/Semedo staying a bit too deep our right side rarely creates danger. The opposing LB can just step out to our RB which often results in pointless passes between Rakitic and our RB.
4. Coutinho's role does not suit him. Coutinho is a playmaker who needs options in front of him who he can pick out. His only options in this system are half space switches to Messi or pointless passes to Alba where they can get isolated easily. Messi at least has Alba who he can pick out but Coutinho does not have anyone on the right side. Also, he is often forced to receive the ball with his back to the goal and with a defender behind him since no one pins the defenders back. Due to his weak stature it's only logical that he often loses the ball in these situations.
The simple change to the system suggested above solves all these problems.
1. It instantly creates better connections due to more diagonality and triangles while still maintaining the stability provided by three deep midfielders.
2. Suarez' and Dembele's positioning between the center back and full back pins back the entire defensive line with only two players which frees up spaces and provides depth
3. Our right backs deep position is not a problem because the opponents LB can't step out without getting exposed by dembele.
4. Coutinho's bad role doesn't exist anymore.
