My issue with the butterfly is that a lot of the players are just dotted around the pitch, leaving free space to exploit. I'd be happy to test your orders with this formation and see if it does well for me. But 4-1-4-1 is what I use now after having 3 seasons of disappointment with the butterfly.
Actually... tell you i am playing against the butterfly tonight in a dead rubber CL match. I will use the 4-4-2 classic and see if he gets anything on me.
