Yeah you don’t need both LB and RB is KKH can cover whereas you do want both LW and RW.
You aren’t finding strikers or CBs better than what we’ve got in our budget.
You can do all kinds of things but if you’re trying to get promoted it’s probably best not to cut off your managers preferred formation for a third or so of games.
I’ve said for a while refs need to study body kinematics as part of training because there’s some cases where a player has either blatantly not dived or blatantly dived based on how they fall that so few refs seem to understand.
