Individual position training approach

[kosto16]

Hello there..i would like to ask how does individual traing works..for example here is the trainig of carrilero and the training of box-to-box

 

 

So does it mean that the player will train mainly the highlighted attributes of each role?
Does the role he trains influence his playing position?for example for this player here it is ''wrong'' if i train him as carrilero and i use him as DLP(s) in DM slot? 

For a player close to his potential is it better to train him in a role that most of his attributes are involved in training in order to stay stable?for example i have a 25yo ST which i use him as AF..is it right or better or wrong to train him as CF(a) and not as AF?

Or for a younger player is it better to train him in early stages in a role that focuses more in the most important attributes?for example a young central defender to get training as DC(d)  and then as BPD(d)?

So many questions here and thank you in advance for every answers i will get.
