I've had success using the narrow diamond against the 4-5-1 V. In theory the ND shouldn't be that effective, but its done well for me.
I would think the 3W-4-3 would be very effective countering the 4-5-1 V although I haven't personally tried it. According to the counter formations table its the counter to the 4-1-4-1. Isn't the 4-1-4-1 very similar to the 4-5-1 V?
Attacking, down the flanks, whole pitch pressing, hard tackling, short passing, man marking, no counter, yes offsides.
nevermind, just saw this topic was from over a year ago!!!
