Thanks mate, I'll try and answer as best I can. To put out a defence, a midfield whose job is to protect the defence and an attack who are there to score goals is not a system. They may all perform as units independent of each other but that's not a system, not until all three work together. I can see how Shaw links up with Rashford or Martial. I can see how Fernandes does the same and more. But the rest, I just don't see it. Greenwood, Fred, Wan Bissaka, McTominay, even Maguire and Lindelof. How do they transition play? Yes in their immediate role they perform, but beyond that there's a real lack of ideas on the pitch and that has to come from somewhere. That's also what I meant by a lack of identity as a team.
Bear with me on this. I see the ball played out to Maguire or Lindelof and then half a dozen pointless passes which serve little or no purpose tactically or territorially. I would understand if it drew out the opposition to create space behind but that's not the case, it's because we have no positional play or idea of how to get the ball forward through the lines from defence into midfield. The most frustrating part is that on the occasions the opposition is drawn out, the ball goes out wide and maybe even into midfield where it hits the next brick wall as the midfield now don't know where to pass, which then allows the opposition to get back and the whole impetus is lost and we either try to force the ball through or pass back or get dispossessed. That to me is a symptom of players not really being given a system or wider tactical approach other than, this is your role.
That leads on to your next question. As a result of all the above we rely on individuals - Fernandes, Rashford, Shaw to create something out of very little. Certainly not something which is created through a passage of passes where players are linking up with each other. How often do you hear any commentator say about us "that was a great team goal"? That's because they mostly aren't.
That doesn't mean the other players are **** or not good enough to play for United btw. It just means they're good in their individual right but aren't being given tactics that enable them to link up with others going forward. So unless McTominay can make a 30 yard run with the ball or Fred can pick a 30 yard pass to Martial, or Wan Bissaka finally manages to lump a cross that finds an attacking player, or Greenwood can weave his way into the box and shoot, those players are devoid of any directions by the manager and coaching team on how to pass and move.
I don't have much criticism of our players tbh. I think they're being limited. Martial should be sold, jury's still out on Fred, but that's about it. The rest are all good enough by and large. Buy another centreback imo and if we sell Pogba, a replacement for him, a striker most definitely. But as I said on an earlier post, we could do all that but if we still continue with the same approach on the pitch it won't have any long-term impact. The funny thing is I don't think we're far off. It's just a change in approach and the way we link defence through to attack.
