Blatantly have to play 3-3-3-1 to accommodate him.
I do think he was inverted to help cover Shelvey and I can see us packing the midfield like that throughout the season. The danger was the amount of space it left for West Ham to attack down the left wing. Also a ton of pressure on manquillo. On the flipside it left Manquillo in lots of space to attack at times.
I'd like to see Fraser, Miggy and ASM behind Wilson. That has the potential to frighten the shit out or defences. I don't that we will though, or at least not very often. The height and strength of Carroll for Wilson to run off was important and we really don't have that height or physicality in Shelvey, Hayden and Hendrick. We have quite a lot of nice options to play around with but we are really lacking a destroyer or another DM.
