Attacking players will be left out no matter what system you play. The ridiculous 4-2-4 that we play to fit as many attacking players as possible is failing.
If Ole is here next weekend, and he has learned anything, he is going to drop one of the front four for an extra midfielder anyway. Then you’d have at most two of Greenwood, Sancho, Rashford, Bruno, Martial, Lingard, Mata, Amad, and Mata, and at most one of Cavani or Ronaldo. Zidane would probably do something similar, with three actual midfielders and three attackers
Conte would probably go with a 3-4-3 and have, again, two of Greenwood, Sancho, Rashford, Bruno, Martial, Lingard, Mata, Amad, and Mata, either side of one of Ronaldo or Cavani.
The difference is that one will have three central defenders and another three central midfielders. The nice thing about the 3-4-3 compared to the 4-3-3 is that the latter needs a DM, whereas against most teams, we can get away with two 8s in the 3-4-3. Also, I wouldn’t say we have more high level CMs than CBs, it’s about the same.
