Philippe Clement has urged Rangers fans to “follow the rules” after the club were issued a fine for the use of flares in their Europa League defeat to Lyon at Ibrox.
The Glasgow club have been charged over £27,000 for incidents with pyrotechnics in their first two Europa League matches, following a similar incident away to Malmo.
“Every time the club gets fines, it’s a bad thing,” Clement said.
“For the club, for everybody working in the club and for the fans also.
“It lowers the budget for other things, but for the fans it’s also really important.
“They need to be smart and follow the rules that are made by UEFA, by the Scottish Football League.
“So they need to follow that, you need to follow also the rules when you’re outside in the city and you need to follow the rules of the police. That’s life.”
Clement’s warning follows interim chairman John Gilligan’s message earlier this week that the use of pyrotechnics “must stop”.
“I know fans want to give their life for this club,” Clement added.
“So I’m also confident when the right people say the right things that they understand that it’s not a good thing for the club, so that they will not do it. I believe in them.”
