I honestly think he'll make as many as 5 or 6 changes. The clues were also in Platt's words the other week when he said "after the international break, you will see the squad come into play" or something along those lines, since we now have games coming thick and fast, with the Champions League and Carling Cup starting. EVERY game we have immediately after our Champions League games is AWAY from home (damn you, fixture 'computer'!), so Bobby will see Wigan at home as the perfect game to mix up the pack, since the other games are much more difficult. I'd expect Tevez, Balotelli, Johnson, Kolarov, Milner and maybe Savic to all start. Replacing Aguero, Nasri, Silva, Clichy, either Yaya or Barry. If Savic plays, it will probably be at right back, with Bobby saving Zab for the Champions League in light of Micah's injury.
