different formations....just look at the pictures...this last one was a 4-1-3-2 vs 4-4-2
believe me I play 4-4-2 most of the time against this type of setting I both lose and win...actually against this team I made a draw 1-1...and I have a much much better team than this guy that won by 3-0 away
I would like to tell you that formation tactics is the bomb...but...
Couple of friends on L17&19 both played with 4-4-2, they have said games are starting to go against them.
I always play the butterfly against 4-4-2. It works well at my level.
