Gianluigi Buffon saved the first penalty awarded by video assistant referee (VAR) in Serie A as Juventus began their title defence with a comfortable win against Cagliari.
Buffon, making his 620th appearance in the league, denied Diego Farias after referee Fabio Maresca used VAR to award the spot-kick for an Alex Sandro foul.
Juventus were already leading at that point through Mario Mandzukic’s volley.
Paulo Dybala swept in a second for the hosts before Gonzalo Higuain struck.
Juventus are looking to record a seventh straight Serie A title this season.
