Ragnar Klavan gifted Cristiano Ronaldo an opener as his hat-trick helped secure a 4-0 win that put Juventus back on top of Serie A.
Match Reports
Cristiano Ronaldo got his 2020 up and running with a hat-trick as Ragnar Klavan's error helped gift Juventus a 4-0 win over Cagliari, sending the champions back above Inter at the Serie A summit.
Despite a dominant first-half display, Juve - who were defeated by Lazio in the Supercoppa Italiana in their final match of 2019 - were unable to find a way through before Klavan's calamity.
But once presented with a clear chance, Ronaldo made no mistake, keeping his composure to beat Robin Olsen, who was beaten again by the former Real Madrid star from the spot in the 67th minute.
Ronaldo's penalty came after Giovanni Simeone almost snatched an equaliser against the run of play, but a strike from substitute Gonzalo Higuain and a composed third from Ronaldo comfortably ensured Juve made it 30 consecutive home league matches without defeat.
Yet Cagliari's run ran out four minutes after the restart - Ronaldo latching onto Klavan's dreadful pass before coolly rounding Olsen and drilling home.

The home side are on the attack again as Alex Sandro cuts the ball back to Dybala from the byline on the left of the box.
