Yes, but he's a better player than Sturaro or Lemina and could substitute for Khedira or Pjanić aptly.
Our game has no flow at the moment, it's the same old stuff we're seeing for years and eventually opponents will find ways how to stop it and counter it. All we ever do is knock the ball around to the flanks for a cross or pass it straight to Dybala and hope he does something. Only Cuadrado changes games because of his pace and dribbling.
I have a feeling our attack is very solid, and its bound to click at one point or another, especially when Pjaca returns so we can see a proper three-spronged attack with players playing in their natural positions (Pjaca-Higuain-Dybala/Cuadrado). But the thing is, our midfield needs to work the ball better so our attackers can attack space instead of endlessly trying to play one-twos or flick-ons that just aren't working against a defensive setup like Milan's tonight where they all try to get behind the ball and keep their positions while strictly marking our target man.
I think what changed this season is that we're not seeing useful runs from the midfield anymore and we're just not on the same physical and technical level as before. One thing consistent about Pogba was his strength and the ability to intercept passes with his long legs, which he would often make into dangerous counter-attacks. Vidal had insane energy as well as being a pretty good passer of the ball and possesing a wicked shot, which made our midfield much more dynamic and dangerous that it is now. Khedira came in when Vidal left but he was never really a replacement for him, because he's more of a holding midfielder and Sturaro will never be Vidal (I think Lemina might actually come closer). Pjanić is no way a Pogba replacement either in terms of play style. So we switched our midfield without really having something to fall back on to besides Marchisio. Pirlo we could do without even if his brilliance often decided games, but two world-class players like Vidal and Pogba had a huge influence to our team, from confidence and team spirit to the technical stuff like play style and trained plays etc.
