Napoli striker Lorenzo Insigne was held up at gunpoint and robbed as he was driving through crime-plagued Naples over the weekend, his agent said on Monday. Insigne was driving with his wife and two friends late on Saturday when he stopped at a traffic light. A gunman on the back of a motorbike pulled level with the car and forced the four occupants to hand over their valuables. As he drove away, the thief asked Insigne, who comes from Naples, to dedicate a goal to him at Monday night's Serie A clash with Fiorentina, local media reported. Italian media said the masked robber got away with a Rolex watch, jewels and 800 euros ($872.48) in cash.

Second-placed Napoli comfortably overcame the absence of suspended top scorer Gonzalo Higuain to brush aside bottom-of-the-table Verona 3-0 in Serie A on Sunday. Napoli stayed points six behind leaders Juventus, who won 2-1 at AC Milan on Saturday, with six matches each to play, and remain outsiders to win their first title since 1990 despite the win. Higuain, who has led Napoli's challenge with 30 goals, will miss the next three games as he completes a four-match ban for his sending-off and furious reaction in last week's 3-1 defeat at Udinese. Fiorentina's recent dismal run continued when they lost to their smaller Tuscan neighbours Empoli for the first time since 1997, leaving them fifth in the table. Juventus have 76 points from 32 games with Napoli on 70, AS Roma on 63, Inter Milan on 58 and Fiorentina on 56. Napoli hit the post twice and had a goal disallowed before Manolo Gabbiandini headed them in front in the 33rd minute, his fifth goal in only seven starts this season, after Verona goalkeeper Pierluigi Gollini parried Jose Callejon's shot.
