How to beat a 4-1-4-1 formation?

[HULIANO]

So what will you advice me to do?

The problem I think Is that you used 3W-5-2 V-style without ML and MR. Basically, your AMR/AML are blocked by his DR/DL and DMC. Your 2 STs will find it difficult to score if he put DOWN arrows on his DCs. So if your attack is unsuccessful and his team turns it into counter-attack down both flanks, your defense is simply torn down. If he has good ST and ML/MR, any counter attack can bring him a goal against you.

I'd use 3N-5-2 flat Or 3W-1-4-2.

I prefer 3N-5-2, go with attacking both flanks because your opponent has a DMC, you don't want focus passing to be mixed because that DMC can get your ball and turn it into a counter attack.

Because you use 3 DCs, should go for whole pitch and offside trap.

In summary, you can use 3N-5-2 flat against 4-1-4-1, the settings are Attacking, Down Both Flanks, Whole Pitch, Normal, Mixed, and Offside Trap.
