There is absolutely no point in signing any player a cover If they don't get a few games, otherwise when you need them they wont be able to play at the required level
I agree that Kompany and Nasty will probably play the most games, but I think Demechelis and Lescott will get games too.
I hope no one is thinking he will help solve any problems at set-pieces. If we are sticking with the man to man marking job, then he will stick with whoever he is given to mark, and players like Clichy and Zab will continue to get caught out one on one with bigger opponents.
I don't know why Pellegrini wanted to change a system which worked for us. Stupid. Our defence was rock solid. If Mancini had done this, he'd have got a lot of criticism
