Since being promoted to the Bundesliga for the first time in 2008, TSG 1899 Hoffenheim have contested some barnstorming encounters with record German champions FC Bayern München.
Ahead of Sunday's ding-dong at the Allianz Arena, bundesliga.com looks back on five of the best of them.
FCB 2-1 TSG, 05/12/08
Having already clinched the nominal Herbstmeisterschaft in their debut Bundesliga campaign, surprise package Hoffenheim went agonisingly close to claiming the biggest scalp of all at the Allianz Arena. Vedad Ibisevic netted his 18th of the campaign early in the second half, but Bayern fought until the very end, sneaking a 2-1 victory after Luca Toni followed up Philipp Lahm's equaliser with a 90th-minute winner.
TSG 2-2 FCB, 16/05/09
Even without the services of the prolific Ibisevic, Hoffenheim gave a fantastic account of themselves when Bayern travelled to Sinsheim for the first time. After Franck Ribery put the visitors ahead, quick-fire goals from Demba Ba and Eduardo put Die Kraichgauer in the driving seat, only for that man Toni to restore parity on the stroke of half time. Bayern would have moved level on points with eventual champions VfL Wolfsburg with a win, but Hoffenheim held their nerve as the game ended two apiece.
FCB 7-1 TSG, 10/03/12
With a 100 per cent winning record against Hoffenheim and a seven-point deficit to make up on defending champions Borussia Dortmund, Bayern well and truly unloaded on Matchday 25 of the 2011/12 campaign. Averaging a goal every seven minutes, the boys in red were 7-0 up by the time the clock reached the hour-mark, a Mario Gomez hat-trick being the highlight. Jupp Heynckes' charges flirted with double figures, before Bayern midfielder Luiz Gustavo scored an own goal to pull one back for TSG five minutes from time.
FCB 3-3 TSG, 29/03/14
Still searching for their first win over Bayern at the 12th attempt, Hoffenheim were daring to dream when Anthony Modeste broke the deadlock at the Allianz Arena at the tail-end of 2013/14. TSG hopes appeared to be dead in the water when three goals in a blistering nine-minute spell from Claudio Pizarro (2) and Xherdan Shaqiri wrestled back the initiative, but Hoffenheim refused to wilt. A Sejad Salihovic free kick reduced the arrears late in the first half, before Roberto Firmino capped an enthralling contest with a deserved equaliser.
TSG 1-2 FCB, 29/08/15
Early birds Hoffenheim looked like they might upset the applecart once again earlier this season. With Bayern casually playing the ball back towards their own goal from kick-off, TSG's heel-snapping game plan forced an uncharacteristic error from Austrian ace David Alaba, whose undercooked back-pass was duly punished by Kevin Volland - the opening goal clocking in at a Bundesliga record-equalling nine seconds. Pep Guardiola's men then had defender Jerome Boateng sent off, but their legendary resolve won through as Thomas Müller and Robert Lewandowski struck to extend Hoffenheim's Bayern hoodoo to 11 defeats and four draws.
