I stand by my comments from the first few pages (and on the speculation thread) he's just not consistent enough at any part of the game to be worth building your attack around, he's great as a wildcard to get something from nothing every now and then but you just don't get promoted on the back of players like that. What I said on the Hourihane thread holds true here as well, to see past his flaws his positives need to be better than 2 goals and 4 assists in 21 games.
I don't dislike him and I hope he does well wherever he ends up next but he's just not what we needed at all and Bruce sending Green on loan to get him in whilst having so many other problems in the squad is a big part of why Smith is our manager now.
