Celtic are facing more UEFA charges following the use of 'illicit banners' from their supporters during last week's game against Lazio.
A large display emerged in the section of Parkhead that houses the Green Brigade prior to kick-off as the teams walked out of the tunnel for the Champions League tie, which ended 2-1 to the Italians.
Full of several messages, some in English and some in Italian, the main part read: "Antifascist Glasgow Celtic".
Smaller text on the inner circle of the display said 'Brigate Verde,' and 'Lazio vaffanculo'. This translates to 'Green Brigade' and 'Lazio f*** off'.
As well as considering action over the tifo, European football's governing body has noted the setting off of fireworks at the match.
It has been confirmed via the Daily Mail that UEFA's Control, Ethics and Disciplinary body are considering charges after a case was opened against the Scottish champions.
The new charges relate to Uefa article 16.2.e, which states: "The use of gestures, words, objects or any other means to transmit a provocative message that is not fit for a sports event, particularly provocative messages that are of a political, ideological, religious or offensive nature."
It comes just one week after Celtic were fined £23,000 for the use of pyrotechnics in their away game with Feyenoord in Rotterdam on matchday one of this season's Champions League group stage.
The club had asked supporters to refrain from using pyro at any point during the game against Lazio following this fine.
Meanwhile, Celtic are reportedly set to reject Rangers' request for away fan tickets for the next derby encounter between the sides.
It's understood Rangers will look for 800 tickets from the Parkhead club for the next meeting between the teams during the festive period on December 30.
That comes after the Ibrox club offered Celtic the same allocation to their supporters for the first derby fixture of the season at the beginning of September.
