It's depend on your opponent mate.

I'm alway use 451v vs very stronger ND.
I think tactics is 50% and setting order is 50%

my setting is
defend mentality
through mix
pass mix

whole pitch
no counter
no offside
zonal marking

AMR / L up
DMC down

Today i've just face up to a stronger ND, then here's result

Okay so I could go 4-5-1V or 3N-1-4-2.
I am at home and stronger so which do I choose?
