Going to face this guy in the cup today, slightly if not much more stronger than my team

This is his squad. He plays 4-3w-3, but before that he played 4-3w-1-2 and 4-1-2-2-1, and there's a chance that he's going to change his formation, AGAIN.

How to beat this guy? And what is the perfect formation to counter his players?

This is my team btw:
