Maybe consider using the AMC has a 'false 9'? Kind of how Liverpool FC use Firmino, who is their 'striker' but he's really there to pull opposition players in the wrong direction.

Put your AMC as far forward as possible, then use the 'attack' mentality on him so that he runs behind opposition defenders. Put 'attack' mentality on the wingbacks as well. Get your team to Attack or even Hard Attack for the first 30-35 mins if you're watching the game; then change to Attack. The game allows you to have no players in the ST role.

I'd use a formation like this:

-------------AMC
AML-------------------AMR

-------MC--MC--MC

DL-------------------------DR
----------DC----DC

--------------GK

NOTE: I would only try this formation if you have good defenders and a decent GK!
