No butterfly has aml/amr with 1 ST, the aforementioned formation is a butterfly variant, with an amc and 2 ST. 3n-1-4-2 or 3w 4-1-2 would be what i would use against it. I've been using butterfly and butterfly variants more often lately and those are the formations that cause me problems and neccessitate formation changes.
See my latest league match.
I also subbed off gallego at halftime and put on an amc instead and went left flank instead of both flanks. I did this because i was sure he was going zonal marking and wanted to overload a side.
