Celtic manager Neil Lennon has urged supporters of the club to stop making pro-IRA chants at matches.
A minority of Hoops fans have brought the club's name into disrepute by singing IRA songs during games and it is now being investigated by UEFA and the Scottish Premier League.
Lennon told SunSport that it is important the offensive chanting stops and hopes those responsible understand it is hurting the club as well football in Scotland.
"It's important that we put a general message out that these chants have no place around our club," he said.
"To be honest, we are better than that as a club and we always have been, we just don't need it.
"We are and always have been a club open to all and we do not have issues around sectarianism.
"We have our own values and traditions but they do not include these chants.
"We don't want them at matches and they must stop."
