City will be no better this season than they were the last.
Silva - Will be a flop, Small, Flair driven Foreigners rarely make it in the Premier League.
Toure - May add some steel, but thats nothing they didnt have before with De Jong.
Milner - A good player, a fine player for a team competing at their current level, but isnt going to take you from the periphery of the champions league to title contenders.
Theyve done little to resolve their main weakness, being their defense.
Their players will need time to gel, again.
The foreign players will need time to adapt.
Theyve already taken steps to replace their best performers of last year; Bellamy is being ushered to the door and Adebayor, who had a pretty good season, seems destined to be replaced with another target man (Balotelli, Djeko etc).
And on top of that theyre slowly replacing the players who have a passion for the club (SWP, Bellamy, Dunne, Ireland, Richards) with Mercenarys demanding £200k per week.
I really cant see how signing Robinho Mark 2, Toure and Milner is going to take them from 6th place to competing with United and Chelsea, no way.
