The visitors started well and were rewarded after 12 minutes as Kerschbaumer's ball through to Andreas Voglsammer was clinically finished by the German front-man. However, that lead was erased two minutes later by Benedikt Gimber before Marco Gruttner fired SSV ahead midway through the half. A Florian Hartherz own-goal in the final quarter of an hour settled matters despite Konstantin's injury-time goal, his third in four matches. The German league now goes into a six-week winter break with DSC in ninth-place, eight points off the promotion places. In his 17 appearances so far this campaign, Konstantin has scored five goals and contributed three assists.
