How to beat modified 4-3-3 ???

Today I played against a weird 4-3-3 formation. He used:


st-st-st
mc-mc-mr
dl-dc-dc-dr

His quality is about the same as mine and with this formation he beats every formation in my league. Maybe he's switching to other tactics as the game starts i don't know. I played 4-4-2 with passing trough flanks but I lost 2-1. He also had much more shots on goal then I had so it wasn't luck.

4 4 2 would be my choice, maybe change your orders to mixed passing and defensive

4-1-3-1-1 or 4-1-4-1 orrr 4-1-3-2

you can use 422 classic, or can usr 4-1-2-1-2, 4-3-1-2
