Just think about few stuffs that may help you;
1- you could close the defense by moving the DR-DL as a central DC to have x3 DCs and a DR or DL
2-as always, the game is reactive, follow the possession bar, test first if there's a mentality giving more margin, and too the focuss passing. If an option lowers your possession at the same instant after switching a setting, revert it immediately.
3-Once you know which side works, simplify the attack in 2 zones instead of 3. Eliminating the AML for example, keeping the center and right side, you could move the AML as AMC perfectly. The game will assign different powers to zones, so by doing this you can concentrate the power in the zones that matter, because the game will assign animations anyway, always.
Btw I dont believe in formations, as the game doesnt understand this concept as we do, just if you know your team, and you know how can your players play properly, then, use what has been working for you.
Too I would recommend you to pay attention to the ratings, the previous ones, as the engine uses these to create the upcoming scenario, soi you can predict which player will improve in rating terms, so, if theres a sub' which is expected to have a rating improvement, because have a patter like 68686 so you can expect a 8, think about using him.
Good luck.
