Hamburg have been in the Bundesliga since its inception 50 years ago while Bayern joined soon after, and they have been rivals all this time with something special about their encounters, especially for the fans.
Tomorrow [Saturday], the HSV Arena stages the 95th clash between two sides who, after recent results, are no longer poles apart.
"It is always a special game, not only for Hamburg, but for any team in the Bundesliga because everybody would like to frustrate and to beat Bayern, and I would like that too," said Hamburg's Rafael van der Vaart.
"We have a lot of self-confidence at the moment and we are highly motivated.
"We need to be at our best, otherwise we can't win, but we want to show everybody that our win in Dortmund was not a one-off."
Bayern will be out to prove that their home defeat to Bayer Leverkusen, a result which ended an eight-game winning start to the season, was also a one-off, which has put Hamburg coach and former Bayern midfielder Thorsten Fink on his guard.
"Bayern are always more dangerous after a defeat," he said. "They will want to react now and it all comes down to how we cope with them.
"We have the fans behind us and we are in good form, so we have to be disciplined and I think Bayern were harder to beat in their first six games than they are now."
Hamburg have not been as hard for Bayern to beat as they have been in the last six years with not one win for the Bavarians in that period.
That record should come to an end tomorrow [Saturday], just as a new record of consecutive wins should begin for Bayern, according to their forward Arjen Robben, who wore the captain's armband in the midweek DFB-Pokal win over Kaiserslautern.
"We want to start a new streak," he said. "We are up for it and we want to establish our place at the top."
Franck Ribery could be back in the Bayern squad after missing their last two games while Rafinha will also be included.
Hamburg are without the injured Ivo Ilicevic and Petr Jiracek.
