I was slightly worried when we gave Mata and Periera contract extensions. The former passed it and the latter never being good enough. Lingard, as poor as he's been, could probably be a squad player, and would obviously get a lot less stick if he played a lot less.
None of these players are good enough to be starting (could argue even playing) for United. Big reason as to why we struggle to create. And when I say create, I'm not talking about just passers, i'm talking about someone who can actually take players on. Our wingers (if we can call them that) struggle to take players on. Rashford and James do it once in a while, but the two are very inconsistent.
I like a 4231, and hope we carry it on, we just need better 10s/wide attacking midfielders. Players like Maddison, Havertz, Sancho, Zaniolo, Brooks, Van der Beek, Bergwijn. Some of these players wouldn't even cost that much, but I personally feel they would improve our team 10 fold.
