A small band of Rangers supporters set off fireworks late into the night outside the hotel where Celtic were staying.
The Premiership leaders were seeking a quiet evening at the Dakota Hotel at Eurocentral on the outskirts of Glasgow on Saturday night.
But Rangers fans had a different idea as they brought some unwanted noise in a bid to rattle the league leaders ahead of Sunday's High Noon showdown.
The tactic has become commonplace across Europe and followers of the Premiership champions will hope they were heard.
Several loud bangs could be heard in the short clip with supporters letting off the pyro within distance of the hotel.
Celtic supporters will be hoping the brief commotion will have little impact on the action for Ange Postecoglou 's side at Ibrox.
The league leaders know a win will see them six points clear at the top of the table and in a commanding position with only six league games to follow.
The pair will meet again at Celtic Park in the final fixture after the split.
