Hi,

I like 4-5-1 v-style, as many formations like using amc (4-1-2-1-2 narrow diamond, 4-3N-1-2....).
Vs above formations I use target on flanks,while mode,pass and counterattack on/off depend on opponent quality and level,offiside off.
Vs 4-4-2,4-4-1-1 or 4-3W-1-2 I use target mixed,while mode,pass and counterattack on/off depend on opponent quality and level,offiside off.

Vs 4-3-3 I switch to 4-1-4-1,since 4-3-3 is in countering table as an eligible countering formation for 4-5-1 vstyle, even if this has to be analized case by case.

For sure I won't use v-style at all vs 3N-2 (AML-AMR)-3N-2 (ST-ST) ,the official countering formation posted in the table
