Your main goal in countering this formation is
1)dominate possession in midfield by playing formations like4-5-1 v style,3-6-1,3-5-2etc.as he has only two central midfielders it will be tough for him to hold the ball

Whichever strong midfield formation u are choosing,go thru the middle.

If u r going down the flanks,which is another great option as the defenders are completely exposed due to lack of wingers,go for formations like 4-3n-2w-1 and 3-6-1 where ur wingers will be advanced and u will have more midfielders in central positions than the opposition
