AFP, MILAN, ItalyLorenzo Insigne on Tuesday shot SSC Napoli into the semi-finals of the Coppa Italia with the only goal in an eventful 1-0 win over in-form SS Lazio. Italy international Insigne needed just 99 seconds to score the winning goal in a match that saw both teams have a player sent off and Ciro Immobile miss a penalty in the first 25 minutes. Insigne displayed some of the sparkling form that he has been lacking this season when he opened the scoring, weaving past Luiz Felipe before slotting a neat finish into the goal. Visitors Lazio quickly shook off the cobwebs and had a Sergej Milinkovic-Savic shot pushed away before Elseid Hysaj kicked Felipe Caicedo in the box as the Ecuadorian dived for a 10th-minute header. However, Immobile let Napoli off the hook by slipping as he was about to kick the resulting penalty, which finished in the running track behind the goal.
