Neither side have been able to find a breakthrough in the first 45 minutes of the Serie A clash between Napoli and AC Milan, although the visitors have been reduced to 10 men.
There was drama immediately from the kickoff as Lorenzo Insigne released the run of Marek Hamsik through the middle of the Milan defence, but the forward was brought down in the penalty area by Mattia De Sciglio.
The referee dismissed the defender and pointed to the spot, but Gonzalo Higuain saw his penalty well saved by Diego Lopez.
Milan had a decent chance to take the lead when Giacomo Bonaventura found space to fire an effort at goal, but Mario Andujar was alert to the danger and made a solid stop to hold the powerful strike.
Napoli had a good opportunity when Jose Callejon beat two defenders to raid to the byline down the right before spotting the run of Insigne in the middle. The winger lifted a cross into the box for the forward, but Insigne missed his kick at the vital moment.
The visitors should have taken the lead when Salvatore Bocchetti found space down the left to whip a cross into the box for Bonaventura, but the forward's header clattered off the post.
