Napoli had better wingers and wide options, but they all cut in to play possession ball centrally. Likes of Insigne/Mertens were false wingers/2nd forwards that were wingers in name only. Best crosser was Insigne cutting in, but his go to moves as skillfull as he was predictable (more so when they lacked heading presence), more useful in transition when defenses weren't set. Only left Callejon was normal winger in ability but mainly played off the ball running behind lines to cut in to far post.
What I mean with width is how he uses fullbacks mainly, Sarris use of them, for someone that's supposed to be attacking Pep like coach, is super conservative, they are there keep shape/balance and possession. Gameplan is too centralized go have much use for them. Asymmetrical in that one allways stays home and the other attacks little more, but for us it's mainly because Cuadrado is just that gunho in natural attacking ability more then by design. Because if it was something we wanted to use more of, the width, we wouldn't move around possession so slowly and only use the other flank as last resort when they cant go anywhere, usually the long ball to the flank is so predictably slow that Cuadrado cant utilize the space he had prior.
Sandro basically has the Hysaj role. Super boring balancing role.
