odd formation, what tactic to use ?

[Kaydeedk]

Hey Guys
im facing this odd formation in my last 4 matches of the league, his team isnt as strong as me, but he have played draw with almost every team, Ive checked out there formation, but they are totally random.

my team formation is.
4-1-2-1-2 with only DMC ( red arrow ) attacking- Through middle - own half - force counter - and offside traps on

regards Kaydee

ps.
