Regardless of whether they are 7 place in Serie A and City 1st in PL, Napoli are known to have a home fortress, teams like Milan, Inter and Juventus are scared to play there. I mean the likes of Inter last won there in 1997. They just beat Inter 3 nil at San Siro. They are a facsimile of Inter 09/10 in the Champions League campaign. Fast and clinical on the break, well organised defensively and don't require alot of possession to win a game and tie.
