can you explain a bit more.....I've been trying lots of different tactics on fm 14 and I genuinely believe that the secret to winning is in oi and marking.
are you saying don't have specific marking instructions for attack players....St amc aml amr etc...?
sound like you mark the midfielders only?
assume that opposition plays 4-2-3-1.
I mark only the 2 midfielders and do not select particular marking for 3 attacking midfielders and striker.
for instance, if the opposition plays with 4-4-2, i do not mark two strikers and two wingers on the midfield. yet, I prefer to mark two central midfielders. the reason that i prefer marking two central midfielders is, if my players loose the ball during the attack, handling with opposition wingers is more easy rather than midfielders. because, there are two players on the wingers (AML/R and Full Backs). somehow, at least they create pressure and gain some time to cover at back. Yet, if the opposition central midfielders beat any of my player on the midfield position, they will directly gain a chance. therefore, i prefer my central defenders to stand in a certain position rather than marking the opposition strikers.
also, i would like to remind that opposition instructions depends on the skills of the opposition. there is a theory from the past years of FM which seems still works (at least I had good results not in final result always but in terms of improving my defence)
for instance, if the opposition players lacks bravery (below 11) you can select hard tackling.
if the opposition player has high pace, dribbling, agility and balance (15 or above) you should select pressing for "never". because your players should react unflappable and if they are in rush, it may cause a lot of unnecessary fouls; or opposition easily beats your players.
if the opposition striker lacks "off the ball" you can select marking "tight" and if it is high you can select "never".
these are some of the instructions i use.
