re: FIFA 11 on 360

Headers are somewhat tough to score on in general (unless its to Drogba etc.), still they really shouldnt be relied upon to score that many goals IMO.

Chip through ball to the winger
then a diagonal chipped through to one of your strikers

That or a simple 1 2 with the striker in the middle making a run, pop a through ball over the FBs head

I run a 4-2-4 or 4-3-3 and its easy as hell, but I do customize all the att/def aarows to fit how I play

Rarely do I use ground passes once I get into their attacking 3rd
Everyone plays differently though; I just find this to be by far the easiest way to get a lot of SOG
