I always thought it's their Milan.
Juventus = United (biggest club in the country, most national titles, patrice evra)
Roma = Arsenal (style over substance, eternal chokers, players have messi canvas in their rooms)
Liverpool = Milan (live in the past, drool over days long gone, consider themselves contenders every year)
Chelsea = Inter (zero success until cheat mode activated, watching paint dry is more exciting than watching their matches)
City = Napoli (their jersey are kinda similar, tactically inept croud that likes to run and score goals)
