Arsenal recently recorded a famous victory in the Signal Iduna Stadium to defeat Borussia Dortmund in their back-yard. Die Schwarzgelben, who had won the previous fixture at The Emirates, were outdone by a solitary Aaron Ramsey striker - that now sees Napoli and the Gunners sitting in first and second place while the German side look up in envy.
But there is no doubt this Dortmund team has been slightly affected by injury worries this season.
The likes of Ilkay Gundogan, Neven Subotic, Henrikh Mkhitaryan, Marco Reus and Jonas Hofmann have all had time off injured this term - as has Lukasz Piszczek.
The right-back has not played a game since the Champions League final in May - around the same time that Arsenal were actually linked with signing the player. With Bacary Sagna’s contract expiring next summer the Gunners were after a swashbuckling full-back to take his place. The Pole fulfilled that character.
Unfortunately he suffered throughout last season, playing through the pain of a hip injury - a hip operation and the subsequent recovery has left him out of action since the defeat to Bayern Munich in May.
The 28-year-old signed a new deal at the club last month - so you can forget that Arsenal link right now.
But the Pole has recently returned to training, taking tentative steps toward his comeback - and he is relieved at the progress he is making:
"I feel good. There are days when you don't feel particularly great, but that's normal at this stage of the recovery process. I'll definitely be fit for the second half of the season. I want to return before then but, if I don't, I won't be too downhearted."
Dortmund have been utilising midfielder Kevin Grosskreutz in the position and he has been doing a pretty good job in the role.
But if Piszczek was to return to the fold, it would certainly benefit the German side - which would not be great news for Arsenal for instance, as they are in the Champions League together.
But good news Gunners fans, because the player does not look likely to return until the end of December - after the final crunch games against Napoli and Marseille.
