Hoops set to face disciplinary body next month
Celtic have been charged by UEFA following their Europa League Group I match against Udinese in Italy last Thursday.
European football's governing body has charged the Hoops with "the displaying of an offensive banner and setting off of fireworks by fans".
The case will be heard by the UEFA Control and Disciplinary Body on 26th January.
Some Celtic fans held aloft a two-part banner which insulted UEFA, days after the club were fined about £12,700 for "illicit chanting" involving pro-IRA songs at a Europa League game against Rennes at Celtic Park on 3rd November.
Several flares were also let off and one was thrown on to the pitch-side track as Celtic exited the tournament with a 1-1 draw at the Stadio Friuli.
Celtic have already banned for life one fan who was arrested in Italy over the alleged assault of a club steward, and who they say was one of those responsible for the banner.
Hit out
Celtic manager Neil Lennon and chief executive Peter Lawwell hit out out at the "rogue" element within their support on the day after the game.
The club also vowed to sift through photographic evidence to find those fans responsible for the use of the flares, warning that they will take "appropriate action".
Lawwell said: "It is very frustrating. Those people are not Celtic supporters.
"We will weed them out and these guys will not get back into Celtic Football Club.
"One or two silly little juvenile boys doing funny kids' pranks and stuff and it is bringing the whole of Scottish football down."
Lennon added: "My only surprise is that they got the spelling (on the banner) right.
"I am very disappointed, they have let me down, they have let the board, players and background staff down and 99.9% of the support down."
