The return of Roman Bürki for their Bundesliga clash with Arminia Bielefeld on Saturday may improve Borussia Dortmund.
After missing out on Dortmund’s last six games because of a shoulder injury, the 30-year-old goalkeeper made his return to team training on Tuesday. Marwin Hitz, a 33-year-old veteran, has been filling out for Bürki recently.
