The Serie A champion Juventus hammer 4 goals on Cagliary in Monday who can only return one goals back with Christiano Ronaldo score a second half hat-trick to lead them
The Portuguese pounced on a mistake in the Cagliari defence to break the deadlock four minutes after halftime before adding the second from a penalty as he scored for the fifth league game in the row.
After setting up Gonzalo Higuain for the third in the 81st minute, he completed the rout by finishing off a counter-attack one minute later.
The win left Juventus top of Serie A with 45 points from 18 games, at least until Inter Milan, who are three points behind, visit Napoli in the evening match. Ronaldo took his tally this season to 15 goals, including 13 in Serie A.
