We need to lose a couple of players too, at present we have two surplus players re the CL A-list squad even without the suggested purchase of Salvio and another defender.
Sinclair is an obvious candidate to move on, and probably one of Barry or Garcia but not both and if Salvio is signed Milner's place looks under threat.
GK: Hart, Pantilimon, Wright
DEF: Zabaleta, Richards, Kompany, Nastasic, Lescott, Clichy, Kolarov
DEF MID: Yaya, Fernandinho, Barry, Rodwell, Garcia
ATT MID: Navas, Silva, Nasri, Sinclair, Jovetic, Milner
STRIKERS: Aguero, Dzeko, Negredo
That's 24 players but only 22 can be named in the A-list as Richards is the only club-trained player so the other 3 club-trained places are left vacant.
The likes of Guidetti, Johansen, Suarez etc can all be named in the B-List as they fall within the U-21 cut-off date. Boyata would be another club-trained player for the A-list but I'm not sure he's part of Pelle's plans.
