Without a DMC you really should be using "Own Half" pressing style. "Whole Pitch" means your team must make longer, riskier passes, so not having a DMC making extra work for your defensive line.

Turn off force counter attacks as well. There are topics explaining this won't work with attacking or hard attacking mentality.

Personally I would change arrows to:
DL---DC--DC---DR
------------------
---MC--MC--MC--
-------AMC-------
------ST--ST-----
