Issues created by trying to make him more attacking aside, I think teams have worked out how to get past him easily in our current set up. Aside from Greenwood (who also drifts inward) and AWB, most of our team naturally gravitate toward the left. Overload that side, and it frees up masses of space down the right. It often pulls him inside just enough so that one of his primary skills is largely negated. That is, using the line to isolate and block players, make tackles, etc... From memory, the first Brighton game being an example. Chance after chance in the same area.
One of the reasons an established player on the right flank was so important this window. The team is somewhat unbalanced.
I may be wildly wrong, of course. Just what I see.
