Training a defenders attack

[Lualwu]

Hey there, I was wondering if there was a way to train a defenders attack, or an attackers defense for example. If I wanted to shape my team to a certain style of play I would like the left and right backs to have a decent attack stat, hence why I was asking the question.

Thanks in advance!

It is not possible to train a skill of a player...attacking of a defender for example...if a player is a full back, he stays full back for all season...
