Barnes got a fair few assists too and played less than Murray. Similar standard and more room for improvement (and greater effort except in contract years). Only negative is he's similar to Hoskins and if our top target is too maybe we need a different option. I'd keep Barnes though think he'll be solid in Champ.
The point is that if you have a partnership and the senior partner leaves, then you have the unknown factor of will the junior get along with his replacement, or will he take the senior role. Not having seen Barnes play except on the box I can't say but would not be surprised if Poyet goes for a new pairing up-front.
