I actually think a narrow 442 would work. I think our problem, even in terms of our midfield, is that it can be a bit too wide at times.I think we would also benefit from defined lines rather than the flexibility that roaming brings. For example, Bruno can be on the right, on the left, up front or dropping deep. Ole and his team don't have the team moving enough to employ a system that requires that level of fluidity to be effective. 442 ( or really a 4222) with Bruno as one of the 2 10's with sancho, and one of Greenwood or Rashford playing alongside Ronaldo. That way you have more staggered lines, without players having to move out of position in order to get back defensively.
More importantly, it think in terms of our build up, we are a bit too measured. City and Chelsea have the patterns and movement to afford to be measured, as they can always play their way out of the back. But we can't and we should simply accept it. We should focus on getting the ball into the opposition half, where we can either keep possession or press to get it back. We spend far too long in our own half, needlessly trying to keep possession and slowly building up. We allow the opposition to set up defensively. If you open the game up but playing it quickly, through long ball down the lines and goal kicks, the game will open up more for our attackers because the opposition would have to deal with the intensity of the direct ball. Our biggest issue is that our attackers do not receive the ball enough to create an impact. What it feels like atm, is that we are trying to play a brand of football that our coaching staff have no clue on how to properly implement. One big issue that also exists in this is that even when we try to increase the tempo of our play, its through the intensity of the passes rather than moving the ball up the pitch. In order for that to work, we would have to have a very high accuracy of difficult to control passes, and only a few teams have that. This means that on most occassions when we try to up the tempo, our play breaks down easily.
I would play:
DDG
AWB Varane Maguire Shaw
Pogba Fred
Sancho Bruno
Greenwood CR7
