One of the thing that I have realized is, as all players including MRLC / AMRLC and ST is marked at the opposition instructions, your players create spaces for the opposition. Therefore, if you are conceding a lot you may try to select "No specific instruction" for marking for aforementioned opposition players. It radically changed my game.
p.s. I mark only for central midfielders because my midfielders prevent opposition's quick attacks by standing close to them.
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?
