The Partenopei president believes his side have the ability to knock the holders out of the Champions League as they prepare for the last 16 tie
While acknowledging the task ahead against Champions League title holders Real Madrid, Napoli president Aurelio De Laurentiis insists "no team is unbeatable" as the Italian high-flyers seek to cause an upset.
Napoli will face Madrid in the last 16, with the European champions to host the first leg at the Santiago Bernabeu on February 15.
Madrid made it through the group stage with an unbeaten record as runners-up, while they top La Liga with two games in hand.
