Why do people keep name dropping random footballers that we don't even need. We currently have the best squad of players in the premiership. One of the strongest midfields in world football. Are we gonna drop Yaya or Silva for Alex Song? The answer is NO! Will Fellani push them out of the team? NO. Will Martinez be an improvement on Yaya Toure? NO.
Could we use Alex Song as back up? Yes, but we are already fully stocked up in that dept with Gareth Barry, James Milner and Nigel De Jong. So why would we spend 25 million on someone we don't need? Having him sit on the bench, getting frustrated at not starting every game.
We don't need Edin Hazard either. Samir Nasri is the same player, often better in some respects.
The longer we keep this team of players together, the better they will gel. We need an experienced center back as cover for Kompany and Lescott. If we bought Vertonghen, he would relegate Lescott to the subs bench, but we would be unstoppable with him and Kompany at the back.
If Tevez stays, then it's happy days for him and Aguero to tear the footballing world a new arse. Just be patient, we don't need to keep on throwing players ontop of players, it just causes unecessary problems for all concerned.
A minor tweak is all that's needed, not surgery.
