Old fashioned 4-4-2

people say carroll slows our play down. fair enough he's not the fast, poacher in the box type. with this in mind and knowing that carroll does have his uses. if he can stay fit who thinks 4-4-2 is the way forward? with two up front, one being caroll the other sakho if he stays. we then need two similar players to these to stand in when one or other is out. even negredo can do a similar job to carroll. the point is we need a structure, a clear way of going about our games. a two man combo up front with strength and pace combined will always cause problems to the opposition. one up front gets isolated especially against good sides. i say drop all this 5 man midfield or 3 man defence and get about it the old fashioned way. if so, we need to go out and buy players for the system and not the other way round.
