ROME, Jan 21 (Reuters) - An early solo goal by Napoli's Lorenzo Insigne gave them a 1-0 win to knock out holders Lazio in their Coppa Italia quarter-final on Tuesday, which also featured a bizarre penalty miss by Ciro Immobile for the losers.
There were also two red cards in the first half hour and both sides hit the woodwork twice in the second half while Lazio had two goals disallowed in a remarkable game.
Insigne gave Napoli, who had lost their last three Serie A games, a much-needed boost when he collected the ball on the left, skipped past his marker and side-footed a low shot past Thomas Strakosha and into the far corner after two minutes.
Lazio won a penalty in the 10th minute after Elseid Hysaj bundled over Felipe Caicedo but Immobile, Serie A's leading scorer with 23 goals, slipped as he ran up to take the spot kick and scooped the ball harmlessly wide.
Hysaj, who had been booked over the penalty, lunged into Immobile and was given a second yellow card after only 19 minutes but Lucas Leiva followed for Lazio six minutes later.
