Has playing a DMC worked for you defensively?

Interested to know if anyone who was shipping lots of goals, decided to implement a DMC in to their formation, and then saw an improvement in conceding less goals?

I currently play a 3-5-2 as per the screenshot below, but seem to be letting in more goals than I used to. This could be because I used to play the above formation but with a DML and DMR instead of a ML and MR but I made that change as I was struggling to score goals in the first half, then was pushing the DML and DMR up the field anyway in the 2nd half, so I'm wondering whether to drop out one of my centre midfielders for a DMC. Thoughts people? Also be interested if people think i might have a few too many red arrows on my midfield players?
