He did, however, manage to grab an assist for Paulo Dybala's late goal.Matthijs de Ligt - 7/10The Dutch centre-back was calm and composed throughout for Juventus. He dealt with the pace of Kevin Lasagna very well and is slowly getting back to his best once again.Leonardo Bonucci - 8/10Bonucci showed his class once again as he put in a superb performance. The Italian CB organized the Juventus defense brilliantly and made a crucial clearance in the first half to deny Udinese's Pussetto.Alex Sandro - 6/10Given a license to roam forward by Andrea Pirlo, Alex Sandro seemed to have his crossing boots missing as he wasted plenty of opportunities to put good crosses in.
