narrow diamond, wide diamond, if you usually play such formation.
it might be stupid to say but to play Narrow diamond your LRD need to better than your CDs, pour Wide Diamond, AM or DM would be the best player in midfield.
if you play 451V ----> move your 2 LRAM to AMC attack through the middle. make sure that you don't make red arrow in your LRD
don't play any assysmetric formation, ultra attacking, ultra denfisive againt 442
