Need Tactical advice vs. strange formation

Hi, i have an away match vs. the strongest team in our group.
He plays a strange: 4-DMC-x-3AMC wide-2 S
Scored 59:12 plays offensive with around 20 Shots ever match.

I would like to play: 3N - 3W - MC - 2 AMC - S
But i have no idea what tactic to choose. DEF with counter... offensiv with defense Bonus...
He is about 5% better then me.

You could try 4-5-1V

I see your tactic proposal. I can tell that you are frightened by his tactic. Dont give him that opportunity to play at your own half. Play 4 defenders with arrows up? Maybe it is good to play with offside on.
