Not sure how what I said is theorycrafting while what you said is a perfectly valid argument... There were a lot of moments in recent big games when we were being pressed high up the pitch and Cesc provided that extra outlet to make sure we didn't lose possession, and extra player to pressure in case we did.
Not sure if we are watching the same games. He doesn't add much midfield control and "not losing possession" at all. Manchester City came attacking in Camp Nou and we had 54:46 possession numbers. El Clasico was as frentic and end-to-end a game as you will see anywhere this season. Again: no control. His "pressing" doesn't add anything. He's literally the easiest player to bypass in the entire squad. This is all that happens when he tries to press:
This 4 midfield formation is just there to please the big names, especially Fabregas, who wouldn't start a single big game if logic were to be applied.
Neymar is not comfortable on the right. He thrives on the left. Neymar on LW > Iniesta on LW.
Alexis and Pedro > Neymar on the right.
Iniesta > Mr. Fabregas in the middle.
2 natural wingers = penetrating runs behind the backline, keeping the fullbacks honest, pressing and tracking back on the flanks.
4 midfielders = Messi runs with the ball in offensive transition, stops, turns around and waits until someone bothers to occupy the left wing.
We're winning inspite of, not because of 4 midfielders. This is pretty much Tito's favourite lineup that everyone hated last season. Except Neymar instead of Pedro on the right wing. lol
