The former Arsenal man had stolen the headlines after tormenting Mauricio Pochettino’s men in London, but his superb showing was questionably celebrated by the German side’s camp.
Niklas Sule opted to scythe down Gnabry amid the full-time celebrations, before Javi Martinez cruelly booted the 24-year-old’s hat-trick ball into the crowd.
As Bayern’s players revelled in the moment in front of their Travelling contingent, Sule comically wiped out Gnabry and left him in a heap on the turf.
The electric winger then attempted to collect the match ball, which should have been awarded to him after his trio, but Martinez had other ideas.
As Gnabry watched on, the former Athletic Bilbao man cannoned the ball into the crowd, leaving his teammate having to plead with fans for the return of his souvenir.
