i think you should able to figure it based on what i've explained in this thread
i already explain what high/low pressing meaning and about zonal/mantoman marking
and i already explain that critical analysis on opponent player and to compare each of your player with opponent player is required if facing equal or stronger opponent, so you can decide is your defender strong enough to having man to man fight against your opponent attackers?
and the key to play effective and efficiently is to focus the passing at opponent weak spot and protect your area that opponent strong in attack
you don't really need DMC if your opponent don't use AMC or non of your opponent player will enter their AMC zone, so what is the function of your DMC if there is no opposite player for him to marked?
and you can using the AMC or order one of your MC to go forward to the AMC zone when attacking if your opponent don't have DMC,
if you can understand all those thing, you can choose the suitable tactic against any type of opponent by yourself,
