4-4-1-1 is quite similar to 4-4-2 classic, but because he using amc and 1 striker i assume he will focus passing through the middle. 4-1-2-1-2 Narrow Diamond is effective againts this formation since this formation dont have dmc. Narrow Diamond also has 1 dmc and 4 defender its clearly can defends well again 1amc and 1st. Go for normal mentality, mixed passing , focus through the middle, zonal, no ca, no offside trap, no arrow.
