Are u having those trouble against team with AML/R or Inside forward?? 4-3-3 or 4-3-2-1?? Then it's the same with me... At first I encounter team with AML/R, AC Milan in serie A, got trashed 4-0.. Next, Benfica in Champions League, 6-0!!!!!!! I reload the game, I save before the match, and using the counter version, 4-0!!!!!!! Reload again, I tried to tweak a little, by making one of the BWM to defend duty, 2-1!!!! I tweak again with FB change to support, 2-0!!!! The pitch is max (like andrichband recomend in first page), maybe the other teams use that at their advantage, using the pitch and play with wingers, the problem is: THOSE WINGERS ,in their formation, is really DEADLY!!!
For me it's usually a long ball over my defenders that a striker or a winger runs onto and easily puts past my keeper.
