Are ML/AML and MR/AMR required to be succesfull?

Really? Care to back that up? Are 4-1-2-1-2 ND and 4-3N-3 useless formations then?

Ok, i'll try to back it up.

No they are not useless.
But i don't think you can win a league playing the same formation every game.
If you are also in CL and Cup, and have similar value opponents in League, i think you need to change it up, sometimes.

For me, those times are, vs 4-1-2-1-2 ND & 4-4-2 flat.
This 2 formations have made me very sad sometimes

Against ND, i used to start the game 4-1-3W-2, and if it didn't work, during the game, changed it to 4-5-1 V_style.
Now i will use the 3-N-5-2 V-style, as the 2 formations above do not work anymore for me.
They did work, last season, in the CL final, none the less...

Against 4-4-2 flat, i use my standard 4-1-4-1 formation. (red's on MR/ML)
But if the statistics are in the favour of the 4-4-2'er, i change it up to 4-5-1 V-style, ingame.

So for me, having MR-AMR & ML-AML in my team, is 100 % neccessary, and 100 % useful, if i want to succeed.
