Not only the illegal formation, but he had three or four players playing out of position.

Does anyone have experience against something like this?

My team is a couple stars stronger than him and I have beaten twice before this while he played more conventional formations.

I played a 4-4-2 with no arrows and normal orders against this formation. I changed arrows and orders to get much more offensively aggressive after he scored. I also made a substitution because this typically seems to produce a scoring chance. But nothing worked.

I am at a loss with what to do. He goes back to playing conventional against others, but is now set up in the illegal formation again for our match this afternoon. Any ideas at all would be appreciated. Thanks.
