Barnes will no doubt get you 15 goals a season in the championship if played as a forward. The problem is he was constantly being played behind the lone forward where he is average. I gather OG likes to play one up top as well and Barnes wont be starting over Ulloa so it looks like replacing him...
I don't have this much info but I do know its a number of clubs inc one prem club interested. A lot of these deals have too many dynamics but if the price is right then sell.
What's he worth £2mill tops?
