Despite resting Cristiano Ronaldo ahead of a crucial Champions League match, Juventus romped to a 4-1 victory over Udinese in Italy's Serie A on Friday with teenager Moise Kean scoring twice. Kean, who received a standing ovation when he was replaced near the end, also won a penalty which was converted by Emre Can. Blaise Matuidi added the final goal as Juventus extended their lead in Serie A to 19 points. With Juventus needing to overturn a 2-0 deficit against Atletico Madrid next Tuesday in their round-of-16 tie, Massimiliano Allegri rested a number of key players. The 19-year-old Kean was handed his first league start of the season, having played just a handful of minutes in two substitute appearances, and he certainly staked his claim for more time. Kevin Lasagna netted a late consolation for Udinese.
