He's clearly seen your squad and your best players are your LM and RM. He's countering the talent, not the formation.
Try the hexagon and play your 6 star left mid attacking mid. I have been beaten by a 4-4-1-1 with the attacking mid was a striker.
Only advice I can give.
Edit: Say his DMR's speed is 50, your LM who will be playing AML's speed will be 60, right? You'll beat his wing backs and open him up.
