MILAN: Edinson Cavani scored his league-leading 18th goal in Serie A this season to take Napoli to within three points of leaders Juventus as Parma lost their unbeaten home record on Sunday.

Juventus had spurned the chance to secure an eight-point lead on Saturday when they were denied a last-gasp penalty in a 1-1 draw at home to Genoa.

Juve coach Antonio Conte later called for referee Marco Guida’s resignation after he refused to point to the spot when the ball came off the forearm of Genoa defender Andreas Granqvist in the final minute of injury time. “The rules are clear, the arm must be close to the body. In such cases, you have to hand in your refereeing licence,” said Conte.

Juve president Beppe Marotta hit out at the fact the referee originates from near Naples.

“Making him officiate Juve isn’t putting him in the best possible conditions. Furthermore, I ask myself what is the point of having six officials if the referee and goal-line official are not on the same wavelength?” he said.

Genoa president Enrico Preziosi, however, suggested Juve’s outburst was wide of the mark.
