This season, they've beaten Liverpool. In the last month, they've beaten Juventus and Inter Milan. Next up, they've got Barcelona and if they weren't Napoli, Lionel Messi and Co might be a bit more worried about being knocked out of the Champions League.
It has been an extraordinary season so far at the formidable Stadio San Paolo stadium, the venue of the first leg between the two sides on Tuesday night.
Where do you start? Yes, Napoli inflicted a rare defeat upon Liverpool in September in a Champions League group match with two goals in the last 10 minutes capping an assured display by Carlo Ancelotti's side.
