I think this is a misconception though that you have to pick certain players because, well they are good. The balance of the team has to always come first. In fact we have an awful build squad which is in large parts the reason why we have now been struggling for ages years now. Rashford, Greenwood, Martial, Ronaldo, Cavani are all essentially strikers, some of them can play in wider positions but their instinct is all first and foremost to score themselves. Letting out Sancho admittedly is something that irks me, since he is the so long needed creative input from a wide position. That he isn't in the best form of his life right now and is struggling a bit is true, but he won't overcome it by being benched because we play a formation in which there is no room for him.
When it comes to the midfield, it is what it is right now, and we probably won't be able to do something about it until next summer, so we need to find a way to get a balanced team out there and if that means to play on the counter for now, so be it. But what we can't keep doing is playing 4 strikers, do horrible gap exposing pressing and be confused about why we get slaughtered.
