I have searched through the whole forum and basicly no one seems to know an efficient counter to this formation. Obviously you want to attack down the flanks.

4-5-1 V and 4-3N-2W-1 are about the only suggestions I have seen but no one has confirmed them with either results or second the suggestions.

I have used a 4-5-1 V and barely got away with a victory so I can't say it's some kind of amazing counter to it. First half I was down 0-2 but turned it around to 3-2 by going all out attack.
