Weston McKennie sealed the match 11 minutes from time on Saturday and the American - a Harry Potter fan - marked the goal with his usual wand celebration.

It was a complete contrast to Paulo Dybala's distinct lack of celebration when he scored the opener in the first half.

The forward, who is embroiled in ongoing lengthy discussions over a new contract, instead gave an icy glare towards the directors' box.

Juventus moved level on points with fourth-placed Atalanta, who have played two matches less than the Bianconeri. Udinese remained four points above the drop zone.

Massimiliano Allegri's side sought to bounce back from defeat to Inter Milan in the Italian Super Cup midweek.

And it took the lead in the 19th minute. An Arthur through-ball found Moise Kean, who laid it off for Dybala to sweep into the back of the net.

Dybala had a gilt-edged chance to double his tally in the second half when he was found by McKennie but the Argentina international fired wide of the left post.

McKennie also missed a header but wasn't going to waste a similar chance moments later as he headed a Mattia De Sciglio cross into the top right corner.

Ciro Immobile scored two goals and had a hand in another as Lazio won at last-placed Salernitana 3-0.

Immobile scored his two within three minutes early in the match. Manuel Lazzari added a third in the second half.

Lazio moved to sixth place.

Earlier, Torino fought back to win at relegation-threatened Sampdoria 2-1.
