Cristiano Ronaldo scored twice – his 13th and 14th league goals of the season – as Juventus beat Udinese 4-1 to move up to fifth in the table.

Ronaldo opened the scoring in the first half and after Federico Chiesa made it 2-0 early in the second period, he added his second.

Udinese, who saw an early effort from Rodrigo De Paul overturned by VAR, scored a late consolation through Marvin Zeegelaar before Paulo Dybala completed the scoring in added time.

Roma remain third thanks to Edin Dzeko's solitary goal at home against Sampdoria and Napoli climbed one place to fourth after a 4-1 win at Cagliari.
