There can be no messing from this game onwards. No place to hide for any player.
Get back to a stable set up and rebuild from it. We have to start with 442, we have to put square pegs in square holes. Can this be done with our squad ? Yes it can. Other clubs play 17 or 18 year olds because they have to, we have to. For one Charlie Barks CB would be fine alongside Manny for a few games while the others realise the team doesn’t revolve round them.
But the priority is getting the basics right. Trap a ball / Control the ball / Pass the ball with pace. Then players give options by movement off the ball.
