Beating a stronger opponent?

So my formation should look like this, except with AMC replacing the AML? What tactics to use and arrows?

You could play like this when your main attacking player is AML. Defensive, via middle, short or mixed, CA on,
MR at MC region. MC slightly moves left, as well as ML in between MC region & default position (to create an equidistant for better control with AML positioning)
Can start match with back-5, and depends on how match flows and moves up DC/DMC to DMC position (or in between) if match control is there.
Since opposition is highly likely to play attacking from a 4-2-2w-2, it is easier to sit and defend for counter goals.

Okay, I will try that and I'll let you know how it goes.
