To help you prepare yourself adequately, bundesliga.com brings you the guide to the mouth-watering Matchday 15 action.

#BMGFCB

Look no further than BORUSSIA-PARK for the event of the 1970s, reloaded with a modern-day spin. Borussia Mönchengladbach and FC Bayern München were the annual antagonists 40 years ago and their rivalry has returned in recent years. The Foals managed to go both the 2011/12 and 2014/15 seasons without losing to the Bavarians – which is no small feat given Bayern's recent form. They come into this clash off the back of a nine-game unbeaten run, while Bayern have not lost yet all season.

#WOBBVB

Jostling for position behind Bayern right now are Borussia Dortmund and VfL Wolfsburg, whose clash this weekend is a 'six-pointer' in every sense of the term. Should the Wolves extend their remarkable unbeaten record at home to 30 games, they can take a chunk out of their opponents' seven-point advantage. Defeat, however, would see that gap grow to ten points, hence the 'six-pointer' adage: not only does the winner stand to gain three points, they ensure their opponents do not pick up any. Watch out for goals, too, with the league's leading scorer Pierre-Emerick Aubameyang (r.) on the prowl among the Wolfpack.

#BSCB04

To complete Saturday's trio of top-six encounters, high-flying Hertha Berlin host Bayer 04 Leverkusen at the Olympiastadion with precious little to choose between them. Salomon Kalou has helped the Old Lady burst through the 20-point mark three games before the winter break, while Javier 'Chicharito' Hernandez has been keeping more than just Die Werkself fans entertained. At the same time, two of the meanest defences in the Bundesliga will be keen to keep both attacking protagonists quiet, making for a sabre vs shield battle to remain on course for European qualification.

Hesse on the map

The German state of Hesse returns to the footballing landscape this Sunday with the first Hessenderby in over 30 years. While Eintracht Frankfurt have been ensuring fans all around the globe knew where Hesse was in recent years, they have been joined in flying the state's red and white flag by SV Darmstadt 98, whose last meeting with the Eagles was way back in April 1982. On Matchday 14, they became the region's leading side, trading places with Frankfurt in the standings. It took them 33 years to get there, but how long will that superiority last?

Former champions in relegation fight

In 2004 and 2007, the Bundesliga was not won by FC Bayern München. It was not won by Borussia Dortmund either. No, it was not the year that VfL Wolfsburg broke the two modern-day powerhouses' grip on the title either. Instead, 2004 was the year that SV Werder Bremen pipped Bayern to the title by beating the Bavarians in their own Olympiastadion home, while in 2007 it was the turn of Armin Veh's Stuttgart to lift the ultimate prize in German football. Although only 11 and eight years ago respectively, it seems an eternity since Bremen and Stuttgart were challenging for silverware, and their current plight is a far cry from those heady days. Their clash on Sunday comes under a different star: a relegation one. Both need the points to seek a safer position heading into the final two games of 2015, in the hope that 2016 can herald better times once again.
