Paul Pogba scored a typically majestic goal to set Serie A leaders Juventus on the way to a 2-0 win over Chievo while troubled Inter were booed off by their own fans after losing 1-0 to Torino with the last kick of the game.
Former Argentina forward Javier Saviola scored his first goal for Verona in a 1-0 win over Atalanta and there was another goal-line controversy in the 1-1 draw between Sampdoria and Palermo.
Juve struggled for an hour to break down lowly Chievo before Pogba glided past an opponent and scored with a low, left foot shot from the edge of the area.
The Frenchman also played a large part in the second goal when his volley, following a superb piece of control, was saved by Albano Bizzarri and Stephan Lichtsteiner netted from the rebound.
Titleholders Juventus, who have 49 points, extended their lead to seven points after second-placed AS Roma were held 1-1 at Fiorentina, their fourth draw in five Serie A matches. Third place Lazio and Sampdoria are level on 34 points.
Inter were booed off at San Siro after Emiliano Moretti was left unmarked to head in from a corner in the fourth minute of stoppage time, giving Torino their first win away over their opponents since 1988.
