Where would you play him alex? Up front with one partner or in midfield?
If you play him up front he drops deep and leaves his partner very isolated. His contribution from deep is not good in terms of his pace, passing etc. Granted he can hit a nice shot now and again and makes a pest of himself when he's in the mood. He's not prolific enough in this league to score you any more than 15 goals max as a centre forward in the Championship (including pens). In the Prem, that probably equates to 6-8. Therefore, you need to have a goal machine, who can play on his own, alongside him to counter balance him.
In midfield, he cannot hold his position whether wide or central. He has poor passing skills, has no pace, his tackling is poor. He gets wound up when challenged by opponents far too easily. I just don't see the point?
I genuinely haven't got anything against Hume. I just don't see the point of him in a 4-4-2 system. IH isn't going to change that system for him so he's got to fit into it somewhere.
