Two goals from Brazilian superstar Ronaldinho lifted AC Milan to a 3-0 drubbing over Juventus on Sunday, while Inter continued its winning ways with an amazing 4-3 come-from-behind win over Siena.

Veteran defender Alessandro Nesta scored in the first half, while Ronaldinho tallied twice after halftime to push Leonardo’s team eight points behind league leaders Inter, who defeated last-place Siena on Saturday and skyrocketed to 45 points.

AC Milan, who have 37 points (with a game in hand) after 19 rounds and play Inter Jan. 24, gave Juventus its fourth defeat in its last five games in all competitions.

Earlier in the day, Napoli surged to third place — tied with Juventus with 33 points — after Argentine striker German Denis scored the lone goal in a 1-0 home win over Sampdoria.

Napoli, who are hoping to snag a spot in next season’s Champions League, have gone a staggering 12 league games without a loss under new coach Walter Mazzarri, who replaced Roberto Donadoni in October.
