He would do much better in a classical 4 man defense. I think with that in mind we've signed him initally, but then Conte left and a lof of things changed. No Conte, no Iturbe, no 4-3-3.
Still a solid signing for depth though. He is doing okay.
Don't think i'd be giving him Asamoahs place in a 3-5-2 but he's so much better than our last full back depth options in the last half a decade, or in fact more.
