Bayern Munich have conceded just two goals since the start of 2013, both came in their last two matches.
These two teams met in the final of the competition last season, with Dortmund recording a 5-2 victory over their rivals.
Legendary coach Ottmar Hitzfeld won this trophy three times with Bayern, but never during his six years with BVB.
Borussia Dortmund have lost just once in their last seven meetings with Bayern Munich - in the Supercup in August.
Mats Hummels started his career at the Allianz Arena, and moved to BVB in 2009, initially on loan.
Ten of the 19 players called up to Germany's squad for the recent fixture against France play for one of these clubs.
There may be a hefty gap separating them in standings, but Bayern and Dortmund are incredibly equal teams. The visitors have a knack of raising their game on the biggest stage, and I'd expect this one to go all the way.
