There are 2 versions of the tactic can be found at the OP : V9 and V10.
I find that V10 is better than V9 but ONLY if you set "Specific Man Marking" before every match. More information about how to set the "Specific Man Marking" can be found below.
ML should be right footed.
MR should be left footed or have "Fairly Strong/Strong" rating for the left foot.
