Neil Lennon wants the travelling fans to behave when they visit the Highland capital of Inverness on Saturday. Celtic have been charged by UEFA for "illicit chanting" during a Europa League game against Rennes and the SPL are also investigating alleged pro-IRA chants in a game with Hibs.
Ahead of heading to the Highlands, Lennon said: "I love this club and I don't want to see its name tarnished by, I have to say, a small minority of fans who aren't doing the club any favours. We are already up on a charge and we have to see what the outcome of that is. I have to say that 99 per cent of our supporters are second to none, they have a fantastic reputation and they do themselves and the club credit, but it is something that is not doing us any favours, not just on the domestic stage but on the European stage. I would appeal to those people to just stop it now and add to the colour and atmosphere that they always do. It is important that the club's reputation is maintained."
