My problem with this "system" thing isn't that it's 5-4-1 or 5-3-2 or 5-2-2-1 or whatever it is. They move it around, and are sometimes shown in 4-3-2-1, 4-3-3, 3-5-2 etc. That's fine, it's just a starting formation. My problem with it in its current iteration is that it puts 5 defenders + 1 defensive midfielder on the pitch. This is fine in games where we are the weaker team, or aren't expected to dominate play or break down a lower block. Hence victories against City, Chelsea and good play against other teams that try to break you down.
The problem is when we face games like this weekend, or other games against "weaker" teams, i.e. teams United are expected to dominate play against.
All of that, by the way, is separate from the other issues with the SQUAD. That they constantly show up small, with terrible effort and seem to forget how to handle / pass a ball or move into spaces. And that despite having the forementioned 5-6 defensive players on the field, we are so easy to play though that its laughable. This is a two-part problem imo, both effort-wise and set-up wise.
I don't know what the hell the people in charge should do, but almost everything that is going on now is not sustainable and not good enough. We can win games here and there, if we are perfect on the day. But any drop in concentration, effort or conversely an increase in such from the opposition puts us immediately in danger.
I would hope Amorim, or whoever else is brought in, would start with playing the players we have in their natural positions, and then trying to create movements and structures from that, both defensively and offensively. We have enough talent that SOMETHING should work. And then, if and when we are able to get players to build a BETTER system, then build that then. Don't shoehorn people into positions that clearly aren't working, leading to drop in morale (speculation) and then drop in effort / performance.
It just makes me angry to watch them these days, almost including the games we win.
