I watched the match last night and Juventus is still not able to kill off their opponents. At 2:1 up Bologna kept pressing them and they were even unlucky not to be awarded with a penalty in the injury time of the match. De Ligt fell awkwardly on the ball hitting it with his arm but the VAR decided that it wasn't a penalty. It was an obvious handball but it happened due to the player slipping and falling and there wasn't anything he could do to prevent the contact with the ball. I think that was the reason they decided against a penalty.
