Just wanted to share my experience with 451V. (90% of the time I've outclassed it with 352 flat. And I mean it)
Attacking - Down Both Flanks - Long Passing - Counter ON
Low Press - Normal Tackle - Zonal - No Offside trap.
Train your players well and use defence bonus.
Can't remember losing to 3-5-2F with 4-5-1V. It's the perfect tactic to be destroyed by the AML/R (long balls + counters).
Did it twice in cup this season against Lv+1 oppos of similar quality.
What were the levels of your oppos ?
Club: FC Lomagne
Level: 33
Current Season (44): League (ON STRIKE), CL (N/A), Cup (In - Quarter-Finals)
Previous Season: League (11th), CL (Final), Cup (Last 16)
