Dzeko, Nasri, Sinclair, Barry, Lescott, Kolarov, RSC, Bridge, Maicon. Can see all these guys leaving, simply not good enough.
For second choice LB, maybe go for Luke Shaw or even promote Jeremy Helan.
Resign Kolo for another year on lower wages, he has earned it.
Marquinhos would be good to add the required depth at CB, that gives us two back ups to Kompany and Nastasic as well as Richards who can play there as well.
In central midfield, one of Fernandinho or Paulinho would be good to add some much needed pace and technical ability there.
For attacking midfield, I would get Isco, would give us the pace and width we lack so often up front, as well as an alternate creative option aside from Silva.
Finally, at striker position I would get Falcao/Cavani, I know that is a bit fantasy but they are certainly buyable and we need a truly world-class striker, Aguero is not quite good enough to be in the bracket of world class forwards.
Overall: Marquinhos, Fernandinho, Isco, Falcao, Shaw
That wouldn't be too expensive and there would be plenty of wages freed up for these guys.
