nope mate , you cant play two centre forward in that manner if you play also a trequartista (silva) and a central attacking midfielder (yaya). 3 of them would play in the same zone. you instead can if you play 4-4-1-1 , but this isnt mancini set up.
The three of them are 'playing in the same zone' under the current system anyway.
I don't want to sound rude about this, but watching a game on the internet there are lots of things you cannot see and pick up. Toure, Tevez and Silva are often playing in the same areas. In fact, it would not be too outlandish to suggest that when City are in possession, not chasing a long ball after being under the cosh, those three have no proper positions.
For most of the game against Villa, albeit with Balotelli playing in Tevez's position, Toure spent most of his time in the 'centre forward position.
There is an argument for saying that Mancini won't play those three and Dzeco as it compromise other areas of the team. But that argument certainly isn't based around those three players getting in the way of each other.
