Napoli maintain top spot after Lazio thrashing

Juventus's 2-0 win in Fiorentina had put them top on Friday, but Maurizio Sarri's side responded in style to maintain their one-point advantage over the six-time defending champions.

It was a third straight defeat for Lazio whose position in third -- 17 points behind Napoli -- is now threatened by Inter Milan and Roma who host Bologna and bottom side Benevento respectively on Sunday.

Lazio had taken the lead in Naples when Stefan de Vrij scored in the third minute at the San Paolo Stadium from a Ciro Immobile cross, before Jose Callejon pulled the hosts level just before the break.

Napoli's second came from an unfortunate Lazio own goal as Brazilian defender Wallace tried to intercept a Callejon centre on 53 minutes only to send the ball past his own goalkeeper Thomas Strakosha.

Lazio were reeling two minutes later when left-back Mario Rui scored with a long-range effort which took a lucky deflection off Piotr Zielinski, with the Polish midfielder setting up Dries Mertens, back after an ankle injury, for the fourth and his 15th goal in Serie A this season after 72 minutes.

- Atalanta boost -

Atalanta -- who take on Borussia Dortmund in the Europa League in midweek before an Italian Cup semi-final against holders Juventus -- slipped behind Milan after a 1-1 draw under heavy rain at Crotone.

A goalkeeping error allowed Rolando Mandragora to open the scoring for the hosts in the 80th minute on a waterlogged pitch in Calabria, before Jose Luis Palomino grabbed the equaliser -- his first Serie A goal -- two minutes from time.

It was a missed opportunity for Atalanta in the race for Europe, when a win would have taken them up to sixth.

Crotone are four points above the relegation zone in 17th.
