Lucien Favre's Foals have hit form just at the right time to make this fixture one reminiscent of the 1970s, when these two clubs were the coolest on the continent.
bundesliga.com is on hand to ensure you're privy to all the pre-match rumblings from both camps.
Bayern may have a sizeable advantage at the top, but as the Bundesliga enters the final straight, they still need to be wary of a VfL Wolfsburg side refusing to give up the chase. The Wolves will be hoping for a favour from Gladbach, but the real reason the Foals want the points is to boost their own Champions League qualification hopes.

Pep Guardiola: "Gladbach are a good team. They've got a great defence and they also go deep, with Patrick Herrmann or . It's a very important game for us right now. 11 points is a good advantage, but we still have to go to Dortmund and Leverkusen."
Lucien Favre: "Bayern are pretty close to perfection, but every team have their weaknesses. Former Manchester United FC player Paul Scholes said in an interview that Bayern would have a 15-point advantage at the top even in England. We're going to have to focus, think quick and play quick.
