Harry Kane scored in each half as Bayern Munich piled the pain on old foe Hamburg in a 5-0 home win on Saturday.
Kane brought his Bayern tally to 93 goals in 101 games while Serge Gnabry, Luis Diaz and Aleksandar Pavlovic also scored.
Alongside Borussia Dortmund as the only Bundesliga sides to win the European Cup, Bayern and Hamburg have taken different paths since dominating German football in the 1980s.
Bayern have won 12 of the past 13 league titles while Hamburg were promoted last season after seven seasons in the second division.
Goalscorer Gnabry toasted Bayern's "blind understanding," saying "things are going well in the team. We're playing well together, we're moving the ball around nicely".
Gnabry hammered the ball into the roof of the net just three minutes in. Bayern junior Pavlovic finished off a team move six minutes later.
Kane converted a penalty awarded for handball with 26 minutes played. Diaz made it four three minutes later, his fourth goal since joining Bayern in the summer.
Nicolas Jackson came on at half-time, making his debut after moving to Bayern on loan from Chelsea in the summer.
Bayern open their Champions League campaign at home against Chelsea on Wednesday.
The England captain then started and finished off his own move to score Bayern's fifth and final goal in the 62nd minute.
Since Hamburg's last win in Munich in 2007, Bayern have won 16 and drawn three of their home matches in the series, scoring 76 goals to Hamburg's seven, a run which includes two 8-0 wins and a 9-2 victory.
