Only reason is because he is small. If he was 6'2 he would be deeper than Xhaka. I agree about our structure though. It's been so poorly put together and I would argue - even if you include Xhaka - this is a very decent midfield to work with this season so there should be no excuse. Our best midfield structure was against Burnley and that mainly had to do with the technical security in passing and dribbling from all 3 players rather than structure because look how far away the forwards were in that game.
