the normalised system is
am marks tm
cl and cr mark 2 of cf st or s2, lb or rb take the extra if there are 3
lblk marks wide right player
rbrk marks wide left player
al ar mark dl dr unless dl and dr are wide players then they will be picked up by rbrk lblk
bw chase the ball as normal and dont zone mark
attackers only zone mark at corners and freekicks and sometimes in midfield in defensive formations.
dy picks up opposition dy
attacking fullbacks/wingbacks are picked up by wide players when they come forward
gk is always free ( for last minute heroics )
if these cant happened then the system uses one of five fallback zone marking plans.
the idea of the report is to give you a guide as to who on the opposition team will be zone marking your players, you may be able to better matchup your players by maybe using one of the exchange tactics or a gamemod. the idea is to try and make this part of the game more visible. but it is only a guide, if the opposition dont play the same formation as they did the week the report is printed then the info becomes useless.
