It's one thing playing as a 2 for a national team that plays to shut games down and puts a defensive midfielder on the wing - and another for a club team. France's style would literally never be acceptable at United, it's part of why Mourinho failed. We also are going to play Sancho and Rashford wide, not Matuidi on a wing to help cover. We also have our fullbacks go forward and regularly overlap, France uses theirs very defensively. Pogba and Bruno are both attacking midfielders in their style. You can't partner 2 of them in midfield unless they are also naturally controlling types in possession, which they aren't, and you just can't put 2 attack minded midfielders in front of a single holder when your wingers are as attacking as ours. It'll be horrendously balanced and it doesn’t matter who our defenders are, they'll have people running at them all day due to the space that will be available.
And for us, yes I am literally saying Pogba only works as a 10 or on the left. That's why he has had constant critics when used deeper. That's why our midfield has constantly been overrun for years with him deep, he isn't a controlling midfielder, he isn't a dictating midfielder, he is really bad positionally... he just isn't a deeper mid. He's an attacking mid, just like Bruno is. You wouldn't buy Zidane and then play him at the base of a double pivot. You wouldn't do it with Iniesta. Xavi, Pirlo, Scholes would all be capable of it though. Same with Kroos or Modric. It's not a case of nobody has played him there. Playing on the left or as a 10 for us is the most similar role to what he had at Juve. For France he plays against lower league opposition most of the time, and then they play conservative tactics with more bodies behind in tougher games. In the Premier League, it's not a case that 90% of games he's fine. It's more like only 10 of the 38 games a season where we could actually get away with doing that behind Bruno and 3 attackers, of which our wingers do feck all defensively. It's suicidal tactics.
We'll see though. I fully expect him to be sold as I don't see him extending, but if we choose to ride out the last year I think we'll only rarely see him as a deeper mid, especially not in tougher/big games. I think he's more likely to be used as part of the front 4 rotation in any tough game, or more likely is Bruno dropping back even which would provide better balance than Pogba in the 2.
