Lazio and Napoli played out a thrilling 1-1 draw at the Stadio Olimpico on Saturday night.
The hosts took the lead 11 minutes in through Sergio Floccari but Napoli struck in the 87th minute through Hugo Campagnaro as the points were shared.
Lazio had a big penalty shout just eight minutes into the game when Antonio Candreva stormed into the box and was muscled off the ball by two defenders but the referee waved play on.
The opener would arrive just three minutes later though when the hosts burst forward on a swift counter attack and Konko played a perfect ball through to Floccari who controlled it on his chest and rifled it home.
Candreva then worked the goalkeeper with a superb free-kick which the stopper had to gather at the second attempt before he had another shot tipped around the post in the 18th minute.
Napoli attempted to respond 10 minutes later but Zuniga saw his shot saved and Edinson Cavani was denied a chance to head home by great covering from the Lazio defence.
Floccari almost netted his second in the 34th minute when he was left free 10 yards out but his thunderous effort smashed into the woodwork.
The visitors responded with Cavani darting onto a cross from Zuniga but his header came back off the crossbar. Hernanes then saw his goalbound strike clawed away from the top corner as Lazio held onto their lead at the break.
Cavani had a great chance to equalise in the 62nd minute but after turning and getting his shot off, the goalkeeper got down well to make the save.
Controversy arrived in the 81st minute when Federico Marchetti seemed to have brought the ball back over the line when catching a high ball but the goal was not given.
Napoli would get their goal six minutes later though when a corner was met by Campagnaro who buried a spectacular volley into the top corner.
Both sides had late chances with Goran Pandev denied by a sensational save before Floccari rattled the crossbar again as the game ended in a stalemate.
