I won the Triple this Season (3), I conceeded max. 2 Goals in one game.

After the last game today, I made some friendlies to try some counter-formations and all of them worked - beside 4-5-1V. And the worst thing of all, Iost vs 5.2 weaker team. It was a reallife-friend, so we made the following tests with the same conditions every game:
Both: full condition, full moral, no winbonus on friendly, no fans at all.

He always plays:
normal-BDF-mixed-off
low-normal-zonal-off

1st try:

3n-2w(DML/DMR)-3n(MC)-2 (ST)
offensiv-mixed-long-off
low-normal-zonal-on

1:4


2nd try:
3n-2w(DML/DMR)-3n(MC)-2 (ST)
normal-mixed-short-off
low-normal-zonal-off

0:3


3rd try:
3n-2w(DML/DMR)-3n(MC)-2 (ST)
normal-DBF-short-on
low-normal-zonal-off

0:3


4th try:
4-3n-3
normal-TTM-short-off
high-normal-zonal-off

0:2


5th try:
4-3n-3
defensive-mixed-mixed-on
low-normal-zonal-off

0:3


6th try:
4-2n(MC)-2w (AML/AMR)-2(ST)
normal-mixed-mixed-off
low-normal-zonal-off

0:2


7th try:
4-2n(MC)-2w (AML/AMR)-2(ST)
offensive-mixed-mixed-off
low-normal-zonal-on

0:3


Last try:
4-5-1V on my own
normal-mixed-mixed-on
low-normal-zonal-off

3:0 win (He only had 2 shots on target)


So is this possible? Is 4-5-1V "overpowered" or was it my tactic-set? I mean, I used the known counter, but nothing worked.
(I tried it, because I don't can handle 4-5-1V and ND... yesterday I was so lucky to win CL 1:0 - I (4-5-1V) had only 4 shots on target, my oppo (ND) 9. My Keeper saved 7.)
