No!!! Why use such a defensive formation? Please post yours and his team quality. Narrow diamond coqnuers 4-5-1V PERFECTLY as I have won against very superior teams with 4-5-1V. Put red arrows on STs,AMC,MCs. Blue on DMC. Attacking mentality,through the middle,hard tackling,mixed passing zonal marking,own half,offside trap and counter attack tick.
This has worked perfectly for me against 4-5-1V
