Nah the problem is how he is seen and how he sees himself. He isn't a central midfielder. I see him as the same type of player as Coutinho, de bruyne, silva, iniesta, eriksen, etc.. You would never play any of those as part of a midfield 2 especially not in a 4-2-3-1. You want them to work hard defensively of course, but positionally they are clueless if asked to play that role. Pogba thinks of himself as a central midfielder like Modric or Kroos or something, but that's not the case at all. He's awful at playing as a proper central midfielder. In fact he's awful at anything involving playing in our own half. He's an attacking midfielder and can be a terrific one, but has a lot to improve.
Of course, the next issue is how good he thinks he is compared to the reality as you say. He has loads of talent but some awful decision making and looks for the headlines instead of the best option. Shit like away to Burnley or leicester when we have so many counter attacks that he leads and he either chooses to go alone, needing to dribble past someone once just to show off, or be the decisive pass instead of just playing the correct early, easy pass which doesn't get the glamour but is the best for the team. That decision making needs to improve for him to take the step up, but not only that, but how he sees himself as I said. Til then, we'll see shit like this against any decent opposition.
