I would suggest you to stay in 3-4 formations based in AMs and start with some "neutral" orders.
Then try to read the game (highlights, live, stats, presence of oppo manager, some signs) and react.
The gameplay doesn't have the old logic. You can play with the "perfect" formation and orders and get a draw vs much weaker oppo and in the next game with not so good tactics to dominate vs a stronger.
