Whoever says Mehdi isn't Juve material, please expand. If he were to come here he'd battle Camo fiercely for the starting position.
If you were to watch him play with Iran, you wouldn't say he isn't Juve-caliber. He's more than capable of holding his own in the Juve line-up with his blistering pace, and very good dribbling.
He isn't top priority right now in terms of positions needed, but he's certainly worth looking at.
