He stopped Barcelona´s creative force in both games. He was very good against PSV too. He is a quality youngster that already plays on the highest level. He will be a good signing. He still needs to improve though. And he is not 6th choice midfielder, when he didn´t play it was because of injury or rotation, Benitez likes to rotate his players.
He will be a big signing for Juve if he comes. I still hope for another central midfielder though,
but someone who can organise the game, like a playmaker. With these two, Juventus will be very strong.
