Cristiano Ronaldo scored twice as Juventus bounced back from their first defeat of the season to beat Udinese 3-1 and move top of Serie A on Sunday. Ronaldo struck twice in the first half to make it five goals in four games as champions Juve move one point ahead of leaders Inter Milan ahead of their trip to off-form Fiorentina later on Sunday.

Maurizio Sarri's side had taken just one point from their last two league games, falling 3-1 to Lazio in Rome last weekend after a 2-2 draw against Sassuolo the previous week. But Portuguese star Ronaldo tapped in his first after nine minutes at the Allianz Stadium, and burst through to finish off a Gonzalo Higuain cross on 36 minutes.

Leonardo Bonucci sealed the three points just before the break when he headed in from close range. Ignacio Pussetto pulled a goal back for 17th-placed Udinese four minutes into injury time with his close range effort beating Gianluigi Buffon in the Juventus goal.

Juventus play their final Serie A game before the winter break at Sampdoria on Wednesday, before a rematch against Lazio in the Italian Super Cup in Saudi Arabia next weekend. Atalanta fell 2-1 at Bologna just days after the Champions League newcomers sealed their place in the competition's last 16 despite losing their first three matches.

Rodrigo Palacio tapped in the first after 12 minutes for Bologna off a rebound after a Riccardo Orsolini effort came off the post. Andrea Poli nodded in the second eight minutes after the break, before Ruslan Malinovskyi connected with a Musa Barrow cross to pull a goal back on the hour mark.
