Former Italy defender Massimo Oddo says Juventus coach Max Allegri will need to consider a set role for Filip Kostic.
The wing-back is joining Juve from Eintracht Frankfurt.
Oddo said, "We need to see where he wants him to play.
"He is a particular player, he is a pure left-handed. I don't see him as a player capable of making the whole pitch.
"Great foot, a player capable of making great assists but a lot will depend on what Allegri's idea of where to field him."
