Union Berlin vs Borussia Dortmund Prediction
Dortmund are infamous for their inconsistency and they are as capable of impressive results as they are of disappointing shocks in almost equal measure.
It was one such disappointing performance that saw Lucien Favre's appointment terminated after a 4-1 loss as home to VFB Stuttgart.
The Swiss manager was replaced by Edin Terzic and the 38-year-old kick-started his appointment with a win over Werder Bremen.
While Union Berlin might be capable of pulling a surprise on their own turf, the buzz generated by a new manager should see Dortmund go over the line with a comfortable victory.
