Not quite as simple as that. Even on a 'free' this is a very risky deal. He's likely to want a high wage & some security so a 1 year deal may not be appealing. Whilst he played a good amount last season, he has also struggled with injuries in his career, including missing the end of last season...
Defensively a few teams transition into it but from an attacking sense, pretty much nobody & for good reason. Villa are the only ones I can think of that nominally line up in a 4-4-2 but in truth one of the forwards (usually Morgan Rogers) plays much deeper to give the extra man in midfield.
Absolutely not.
When we switched to a variant of it today we looked absolutely lost. It completely took Wright out of the game. We didn't have to worry about Norwich nullifying our threats, we did it to ourselves.
Fair enough, just that you presented something as a statistical fact which was provably false.
No issues with opinions, I can see why some are a bit on the fence with him, a bit like they used to be with Sheaf.
