We said: Union Berlin 1-0 Union SG
Both meetings in the group stage ended 1-0 to the away team, but we can envisage a reverse scoreline on Thursday, with Union Berlin likely to be able to keep their opponents at arms' length.
The two managers deploy very similar formations with an emphasis on remaining compact out of possession, so it may not be a match for the purists to savour. However, the home fans will be roaring their team onto unprecedented success, with Union SG potentially having to settle for keeping the tie alive heading into the second leg.
