Louis you've took the words out of my mouth.
If we lose Tevez then Ibra has to be the signing unless we can pull of something truly ridiculous (Messi/Ronaldo) for all the reasons above.
In my opinion Balo will never be a wide man, he just drifts in and out of the game too much. Then because he's an idiot he gets annoyed at himself and does something stupid. A stat of yellows/reds/fouls out wide compared to when he's playing centrally would be interesting. When he plays centrally he gets involved and surprisingly plays very unselfishly with nice link up play. Was unlucky not to have got a couple of goals in the tail end of the season, some heroic goal keeping kept him out.
The Barry issue is strange. On the surface he's a liability against poor sides, nothing to give going forward and vulnerable to their only outlet; pace. Yet he still seems to monster those games, I would say a good 5 of our away wins were down to a Barry simplicity master class. To the extent I think he's more important than De Jong against those teams. Then again De Jong started to add a decent range of passing to his game. Would be interesting to see if he could step up to be a play maker, he obviously has the technique and has creative experience at other clubs.
As you say though we definitely need one more good midfielder. I'm stuck between the ideal being a Fabregas (Creativity/ideas), a Lampard (Consistency) or a Gerrard (Leadership). Could make a case for us needing any one of those qualities the most and I know each posses a bit of the other's qualities.
Goal scoring winger needs to be fast aswell.
