formation that r not as good as before

[Roger Tyler]

i have notice over these last 3 or 4 seasons that formation i use to use are no way near as good as before. like 4-5-1v and narrow diamond are no longer good against 4-4-2. like last season i lost 2-1 to the bottom of our league he played 4-4-2 and me narrow diamond, his avg 72,3 and mine 78.9. i don't understand why it changed

if anyone found other formation that use to work please share.
