A section of Galatasaray fans unsuccessfully attempted to dig a tunnel into Schalke's Veltins Arena ahead of their Champions League last-16 clash on Tuesday.
Undeterred by a full house and tickets on the black market being traded at prices of up to €1,000, the group of desperate supporters tried to burrow their bare hands through frozen ground under a perimeter fence.
Horst Heldt, sporting director of the Royal Blues, confirmed the bizarre incident prior to kick-off, telling reporters: "Yes, that's right. Some supporters have tried to dig a tunnel with their bare hands."
A 1-1 draw was played out at the Turk Telecom Arena three weeks ago, but Umut Bulut's late winner handed Galatasaray a 3-2 second-leg victory and progression into the quarter-finals of Europe's elite club tournament.
No further comment has been made on the matter at this stage.
