4-5-1 V, defensive counter tactics against 4-3w-1-2.
If losing at half time, change to 3-5-2 V and use normal/attacking mentality, still with counterattack
Down both flanks, mixed passing, no offside, normal tackling and zonal marking.
It worked for me in my CL group stage, won 2-1 and 2nd game was like 5-0
