Celtic assistant manager John Collins says it's "vitally important" fans behave during tomorrow night's Europa League game at Inter Milan.
The club has been fined €10,000 by UEFA for crowd trouble in December's game against Dinamo Zagreb in Croatia.
It's the latest in a number of incidents involving Celtic supporters in recent years, but Collins says a small number are making life difficult for the club.
"Obviously disappointed," said the former Monaco midfielder about the fine. "We had sixty-thousand last week (against Inter), unbelievable behaviour from every one of them.
"Throughout the years the vast majority have been impeccably behaved. Great reputation throughout Europe.
"It's one or two we have to try and weed out."
