Advise on counter to 4-1-2-3 AML/AMR

[Arphaxad]

Yes it is a very good formation vs this opponent.
With your formation you should be careful vs people who play 4-2-3-1 or 4-2-2-2.

Thanks, won 5-0 and 2-0 without even attending as I wasn't able to.

Actually meeting 4-2-3-1 tomorrow. Considering going with 4-5-1v with a DMC and red arrows on my fullbacks. Attack wise, I'm contemplating using a false 9 (AMC) instead of a ST. Either that or 4-1-4-1. Thoughts, @Der_Ryan_M ?
