Fabio Capello has sent a warning to Real Madrid that Napoli could destroy them ahead of their UEFA Champions League round of 16 tie on Wednesday night at the Bernabeu.
The first-leg fixture will be an interesting encounter with the Serie A side firing on all cylinders after scoring nine goals in their last two games, while Los Blancos flattered to deceive in their 3-1 win over Osasuna on Saturday.
Forward Dries Mertens has been at the forefront of Napoli's scintillating displays with 16 goals in the league this season, including an incredible hat-trick in their 7-1 demolition of Bologna last week.
"If Real Madrid make the same mistakes they did tonight [against Osasuna], then Napoli can be as superstitious as they want right now, but Mertens and Napoli will go clear on goal every time," Capello told Fox Sports Italia.
"With the way he runs, Mertens will present himself practically alone one-on-one with Navas. Sergio Ramos, in particular, was just unrecognisable tonight."
