The Azzurri are looking to further reinforce the squad in the summer in order to mount a serious title challenge in Serie A, with the Slovakian reportedly one of their top targets.
Vladimir Weiss looks set to leave Pescara when his contract expires at the end of the current campaign, with top Italian clubs showing interest in his services.
However, it appears that Napoli have an ace up their sleeve, as key midfielder Marek Hamsik is a close friend of the Pescara winger.
The Azzurri seem to have moved to the front of the queue for the talented footballer, who has scored 4 goals and set up as many in 22 Serie A fixtures this season.
The 23-year-old only joined Delfini in the summer, but he is certain to leave the relegation strugglers at the end of the season.
