Munich - In our latest feature, Off the Ball, bundesliga.com casts an eye over the weird, wonderful and sometimes controversial stories to have emerged from Germany's top flight.

With the Bundesliga clubs returning to UEFA Champions League action this evening, it is only fitting that today's edition has an international feel to it...

Arsenal will no doubt have done their homework ahead of their unenviable task against Borussia Dortmund in the Champions League this evening, but do Per Mertesacker and Co know what their opponents' initials stand for? The word Borussia orginally stems from the Latin word for Prussia, but the club's founders took it from a local brewery. It forms the latter part of BVB, or Ballspiel- Verein Borussia (club for ball games) as the team is commonly referred to nowadays.

Promoted clubs usually have a tough time adapting to life in Germany's top flight, but Hertha Berlin are bucking that trend. The signs are good that they are here to stay too, as no side has ever been relegated having amassed 15 points after the first nine matchdays. No team in fourth spot at this stage has ever been demoted either. With a Matchday 10 trip to FC Bayern München however, Hertha fans will not be counting their chickens just yet...

FC Schalke 04 face their toughest Champions League test so far this season, with the visit of Andre Schürrle and his Chelsea team-mates. As if that were not enough, the Royal Blues must make do without star striker Klaas-Jan Huntelaar, who has undergone surgery to correct knee ligament damage. The hitman seems to be in good spirits though, tweeting a post-op picture of himself in his recovery room:
