Unbelievable scenes took place in Germany after Hamburg's elimination from the DFB-Pokal on Monday evening.
The former European Cup winners were convincingly knocked out by Dynamo Dresden, who play in the league below them, during a 4-1 demolition job at the Rudolf Harbig Stadion.
Yannick Stark, Robin Becker and Christoph Daferner fired the underdogs into a 3-0 lead before the hour-mark and it wasn't until the 89th minute that Hamburg managed to breakdown their defence.
Drama in Hamburg vs Dresden
But even when Hamburg eventually bagged themselves a consolation goal, there was a quick response from Dynamo as they advanced to a 4-1 lead with a stoppage-time penalty.
However, the game has made headlines across Europe for an incident involving Toni Leistner who appeared to be recorded entering the stands and confronting supporters after the defeat.
The shocking clip shows Leistner becoming embroiled in a physical confrontation with fans, causing stewards to break up the situation before the defender returned to the pitch.
Shocking footage emerges
It remains to be seen why Leistner took such a dramatic cause of action after his post-match interview, though the footage suggests that the German made a beeline for a particular fan.
That does, of course, imply that unsavoury words were exchanged before the situation escalated into a physical clash. You can check out the remarkable footage down below:
Have you ever seen anything of the likes in a top European competition!?
Leistner, who may be familiar to English football fans for spending time with Queens Park Rangers, was born in Dresden and previously made 21 appearances for Hamburg's conquerers.
Flashbacks to Eric Dier... kind of
The footage will likely remind supporters of when Eric Dier climbed into the stands after Tottenham's FA Cup defeat to Norwich City during the back end of last season.
It goes without saying, however, that the England international didn't go as far as starting a physical confrontation with fans who were shouting abuse at him near his family.
