I face an inactive guy in cup, but he already beat two opponents better than him. I'm afraid^^

He plays 4-3-3, one thread in the formation subforum says "3-5-2, 4-5-1 V and even 4-4-2", the other one says "4-1-4-1" is the counter. What would u use?

I dont want to miss this chance to advance by playing with a bad formation^^
