While the issue in attack is certain players clogging up all the minutes, the problem in midfield has been squad quality and injuries. It is easy to point out that Felix Nmecha’s injury coincided with the squad’s downturn in form and the team clearly misses his ability to receive the ball on the half turn.
This squad building issue may also have Edin Terzic at fault. Emre Can’s poor campaign has come on the back of him being potentially replaced by Edson Alvarez, before being appointed captain out of nowhere. Plus, Terzic continues to insist on using Can despite some of Dortmund’s best performances coming with a two man midfield of Salih Özcan and Felix Nmecha/Marcel Sabitzer.
While neither Özcan nor Can have excelled, the former has often been rotated out unfairly. There is still an issue of rotation in midfield, as Nmecha and Sabitzer seem to be forced into getting too many minutes soon after returning from injuries. BVB do have 19 year old Abdoulaye Kamara who could be given a look in the first-team although this would also be a risk.
Borussia Dortmund should be able to get more out of the players they have, but may have set themselves up poorly in midfield.
