left wingers wing back

hi fellow managers

i have a question.
im playing 343 and looking for a physical strong left winger who can play as a wingback like kostic or acuna
looking at defensive and attacking stats oyarzabal pops up.
can he play as a wingback or do people have another option in mind

You can re-train them to play in WBR - RB positions; but their hidden attribute of Versatility is necessary to be high in order to learn that position as much quick as possible. If you choose to re-train; you will see that the player will re-balance his CA, because those positions have different weighting from MR - AMR positions.
