Granted, I might have overdone the minimalism just a bit. But during my research I sort of realised that there wasn't really much anybody could do with Napoli as a club within the city of Naples. It hasn't got the homely sort of heritage within a borough or district, there isn't much of a crest history to it, all there really is is a white serif N within two differently shaded circles of blue. I simply rolled with it. Gave it some contrast by adding Naples' city colours. Et voilà, Gli Azzurri with a touch of Rosso e Giallo. Transparent file in the comments.
