what is tactical role is fm 2013 training

my coaches keep saying that some of my players need to improve there tactical role,anyonr know what that is?help please

Say you have a central midfielder who's preferred role in his position is Deep Lying Playmaker/Defend. In your tactical system, you can select roles for your players to play. It you can trust your coaches, go on his training screen and select whichever role you are playing him as to train him in.

Sorry if this didn't clear anything up.

i dont know what you mean byt this, iv done all the training things you said but dont know how to do this?

After awhile your player should adjust to the role and you won't get that message anymore.
