Tonight's 5-0 thumping of Greek side Olympiakos ensures Freiburg will contest a Europa League knockout tie in the new year.
The Austrian international turned home Eggestein's 3rd minute cross holding of ex-Leverkusen defender Retsos in the process. Five minutes later he nodded home Ritsu Dōan's corner, only to complete the hattrick after the half-hour mark rising highest to head Makengo's delivery home.
Streich's target man wasn't finished just yet. He turned provider for Sildillia to pull the trigger for 4-0 before the interval despite the best attempts of Paschalakis.
Dōan would add the final touches in the 77th minute on what was a dominant evening for the Breisgauers. The winger pounced on Junior Adamu's pass to rattle the net with a left-footed drive. Freiburg will head to London for a final meeting with West Ham to decide who tops Group A ahead of the knockout round draw.
