Pogba could technically play much better from deep with us as seen with France. However, the balance that France achieve with Kante/Tchouameni alongside Pogba and Rabiot/Tolisso is not replicable with Utd for two reasons...imo.
First, the undisciplined nature of Fernandes. He is a hard worker and with unbelievable output and Creativity and must be in Utds first 11. However, to maximise his positive traits he is given the freedom to roam. Fernandes, while hard working, rarely tracks consistently and rarely holds a standard position. (Looks more like a false 9 this season) If we expected Pogba to play as he does deeper for France, Fernandes would have to stop playing as a free role 10 and be replaced by a more disciplined Midfielder as part of a midfield 3.
Second, Jose had the best chance to at least try play Pogba in a structured midfield 3 a la France with players like Schneiderlin, Herrera, Matic alongside. However, look at the difference in quality between Utd and France both in that midfield 3 (Kante v Matic, Rabiot v Herrera, Tolisso v Scneiderlin) and the equivalent front 3’s at that time ( Any 3 of Rahford/Lukaku/Sanchez/Martial/Lingard simply do not provide the same threat or options at the likes of Benzema, Mbappe, Griezmann, Dembele). Even if Pogba in a balanced midfield 3 Had of worked with say Matic and Herrera, the quality was missing up top.
In short, Pogba for France should stop being viewed as some sort of paradox. Its very simple, he can’t play deep for Utd while we play with a free 10 and not with a balanced midfield 3. Bruno has become essential to our best football over the last two years. We also don’t have the players to play that balanced 3...and Solkjaer doesn’t look to be in a rush to change that.
