Probably, like you, I don't have the answer to that question as, definitely, like you I'm not a football expert with an encyclopaedic knowledge of just who is available and affordable and would consider coming to United. No one on here does.
Unike you, and quite a few others on here, I'm just not going to seemingly lazily settle and be happy to just regurgitate the same tool that flatters to deceive, slows play down and, in general, makes us less athletic and a less potent team whenever he plays. That's my opinion. I've watched him in a Blades shirt for all the years he was here and was glad when he finally left.
The teams at the top are more fluid, quicker and more potent going forward at the moment than we are. Granted that burnley seem to play more on the counter-attack but the way to get promotion now is, in my opinion, to fucking 'go for it with pace and endeavour' whenever we can, not bring in a useless, slow 'tug boat' that prefers an onn-field fight with his opposing centre half than being positive in front of goal.
I suppose we could trot out the old "well, he's brilliant as a defensive header of the ball". Yes, he is but that's not what our primary need is for a new attacking signing.
Bring McBurney back and give him significant game time and we really don't deserve to do anything but stagnate. He's the (regrettable) past.
It's my opinion, that's all.
