Napoli advanced to a Coppa Italia quarter-final against Lazio after beating Atalanta last night.

But the Partenopei's second goal by Lorenzo Insigne left Atalanta incensed.

A ball was played into the box towards a clearly offside Gonzalo Higuain.

As most defenders do, Atalanta's Cristiano Del Grosso raised his hands to appeal to the linesmen.

Unfortunately the Italian had his back to the ball and it bounced off his backside, right into the path of the unmarked Insigne who tucked it in to give Napoli the lead.

Was Higuain interfering with play? You decide...

 In fairness Jose Callejon scored a belter for Napoli's eqaulizer.
