Is Narrow Diamond getting out of controll? (like 4-4-2 back in the day)

[Eugen Cristea]

When i play vs ND, all my players get a -1(minus 1) rating compared to all the other games vs different formations, it doesn't matter if i play against a good or a bad team.
I use 4-1-3W-2, and change it to 4-5-1 V, in game. My normal formation is 4-1-4-1 [doesn't work]
Today i lost 2-1 away in CL vs a team similar to mine in quality, changing between this 2 formations.
And the first 2 matches i won 2-1 and 3-5, against bad teams. But very bad games! (yes, i have 3 ND's in my CL group)
V style is the old counter, and 4-1-3W-2 is the new one, but none of them work )

Is this a problem for other "managers"?

I would really like to win the CL again, and i have the best team so far in the competition.
But there are sooooo many ND's in the leaue, some with decent teams.

So what have you used successfully, in the last season and this season?
