Hi guys, so i want to try out a new formation. it's the 4-2-3-1 that is as follows
GK
DR DC DC DL

MC MC
AMR AMC AML
ST
my only problem with this formation is that my 5 mid and ST are lined up in the opposition half. Will it leave me defensively fragile since i usually play a 4-5-1 V which has a DMC unlike this formation. Also, should the 2 MC have down arrows?
Or would a 4-4-2 give me more solidity than this formation?

Thanks in advance
