Theoretically, I don't have an issue playing 3 at the back, particularly if that 3 are capable of covering the width of the pitch and are able to operate without a spare, covering defender (I'm not convinced we have 3 that can do that). Our main issue when we play a 3 is that playing 4 in front asks way too much of Charles and Jander, they simply don't have the engine, top quality players for the Championship but the task expected of them is too big and we concede control of the midfield when they are blowing out of their hoops, which I think played a part in Jander's missed pass.
If 3 is the magic number at the back, for the love of Mary, put 5 in front - and well fuck me we get 3 top midfielders in the team with Azaz or Leo joining the midfield party. 2 up top, Downs plus whichever midget striker looks like they might hit the barn door. Yes Downs... better he plays with a partner, rather than looking like an isolated waste of money.
I'm not convinced 3 is the magic number for us. 4-4-2 might be considered out of fashion but it suits our squad, should Downs find some form then we could go 4-2-3-1.... yeah stick with 4-4-2 and get Downs to watch Che Adams from 2 seasons ago.
