Philippe Clement has told of his frustration after Rangers were forced off the pitch against Dundee due to a pyro show in the stands.
After just two minutes the away support was lit up with a number of flares before the stadium was engulfed with smoke.
As a result, the ground's fire alarms were sounded and referee Kevin Clancy was forced to halt play while emergency services cleared the arena for play.
Clement was quizzed on his feelings about the pyro after the match live on the BBC.
He said: "It's not a good thing that we need to step inside. We had to break our rhythm.
"I'm not the guy who has to say what the fans are to do but those things are better not done because we want to play football and keep our rhythm. "
