Racist chanting halts game

Suspected racist chanting halted play at the Stadio Olimpico on Wednesday as hosts Lazio suffered a 2-0 defeat that kept visitors' Napoli's sterling Serie A season on track.

Goals by Gonzalo Higuain, the Argentine's 23rd in as many league games, and Jose Callejon combined to keep Maurizio Sarri's men top of the table with a two-point lead on champions Juventus.

But the game was marred by a three-minute suspension in the second half on the orders of match officials for racist and insulting chanting aimed at Napoli defender Kalidou Koulibaly.

Higuain is bidding to beat Gunnar Nordahl's all-time Serie A record of 35 goals in a single, 20-team season (1950) and after spurning an early chance was soon into his stride, thanks to a slice of fortune.

The Argentine ran on to Callejon's through ball on 24 minutes only to see Federico Marchetti come out to block, but as the ball bounced up Higuain chested it home.

Callejon, who hit a brace in a 5-1 thumping of Empoli last weekend, doubled Napoli's lead three minutes later.

Lazio may now face sanctions for the racist chanting.

To make matters worse, Stefano Pioli's men dropped one place to ninth, with Empoli going the other way thanks to Manuel Pucciarelli's leveller at the death in a 1-1 draw with Udinese.

Juventus had a Sebastian De Maio own-goal, from Juan Cuadrado's angled strike, to thank for a 1-0 win over Genoa and a 16th win of the campaign amid what is set to be a tough month of competition on three fronts.

However despite setting a new club record of 13 consecutive wins, coach Massimiliano Allegri looked furious when second-half substitute Simone Zaza saw red for a rash, studs-up challenge that left the Turin giants exposed for the final minutes.
