I simply don’t understand this. Some in Madrid say their derby is El Classico and not against Atleti. Some rags say their true derby is against the dippers, though not many did last week.
Your derby is against your closest neighbours.
Maybe for people from Milan it is different?
Yes, Uffa is right. For AC Milan fans the only real derby is against us (“Derby della Madonnina”). Also because Inter was founded following a split from FC Milan (the old name of AC Milan).
But also for Inter fans, aside those living in Milan, or in Lombardy or elsewhere, derby against Milan is anyway a really important match regardless of positions of the two teams in the championship table. In my opinion, it isn't as at the same level of animosity as the derby in my city, between Roma and Lazio. For their fans “Derby Capitolino” (Derby of the Capital city) is almost the only important match of the entire season, because there's a deep hate that goes beyond the limits and I'm not speaking about behaviour of fringe movements. It varies from simple odd behaviours (some "Romanisti" don't want neither to talk with a "Laziale" and vice-versa, provoking them as inferior human beings) to violence and crimes, above all in the decade where in Italy there was terroristic political activity, in the '70s. Luckily, later youth people understood football is only a sport. In both cases, for fans, winning a Derby is a way to bragging around and mocking the rivals 'till a new Derby is played, but this happens everywhere.
In these very last years derby between Inter and Milan has regained importance it didn't had after 2010, because both Inter and Milan were "killed" by FFP: Massimo Moratti, the Inter's president of the Treble, had no more money to spend and Silvio Berlusconi fell in hard times, politically and with his health, so they both left gradually.
Dipper is Liverpool? What's the origin of the term?
