Borussia Dortmund slumped to rock bottom of the Bundesliga after their 8th loss out of 13 league games, with a run of one win in seven. They bagged a much needed win yesterday, but that just papers over the cracks.
This clearly isn't the same side who reached the Champions League final over 18 months ago, or the same side who ran Arsenal ragged 2 months ago. So what has happened?
Dortmund have struggled for injuries this season, but this didn't stop them when they played Arsenal in the Champions League and had six first team regulars ruled out injured. Their league form however doesn't reflect their European form as they eased past Galatasaray, Arsenal and Anderlecht to storm top of their table.
So many are wondering why their league form has been so dire. Injuries to Mats Hummels and Sokratis have given manager Jurgen Klopp defensive worries. Neven Subotic has been struggling for form after returning from 9 months on the sidelines with injuries, and many mistakes within the back five have cost them. Usually reliable goalkeeper Roman Weidenfeller also at fault for some errors, but it's not just the laughable defending.
The loss of Robert Lewandowski to Bayern Munich has proved costly as they signed no direct replacement for him. This has also dried up their goals going forward, and the man who stepped up to replace Mario Gotze was Marco Reus, who has only played four games this season due to recurring injuries.

Dortmund play with so much creativity and confidence with Reus on the pitch, however without him they lack confidence and invention.
The recent 2-0 loss on the weekend to Frankfurt after another defensive error, has raised questions over Jurgen Klopp's future although he is still adamant he will 'Not resign as manager'. The win over Hoffenheim yesterday offered brief respite but there are still some big questions to answer.
