Cristiano Ronaldo set up Paulo Dybala to score early and added one himself with defender Leonardo Bonucci also on target as Juventus surged 14 points clear in Serie A on Friday with a 3-0 win over lowly Frosinone. Coach Massimiliano Allegri was taking no chances, even against a side sitting second bottom of the table, ahead of next week's Champions League last 16, first-leg tie at Atletico Madrid. Dybala returned to the front line alongside Ronaldo and Mario Mandzukic with key defenders Bonnucci and Giorgio Chiellini both back from injury.

"The team is growing in terms of fitness, it's a decisive moment for the season," said Allegri. Juventus are building towards next week's game in Madrid and a top-of-the table clash against Napoli in the San Paolo Stadium on March 3. "We struggled a bit after the winter break but now we are ready to face this important moment of the season both in the championship and the Champions League," added Allegri.
