Celtic have had somewhat of a turbulent summer up to this point.
On the pitch, results have actually been good. Victory over Linfield sets them up for a Champions League qualifying round tie against Rosenborg this week.
However, on two occasions have they incurred the wrath of UEFA. Fresh charges were brought against them this week after fans unfurled an "illicit banner" during their 4-0 win over Linfield at Celtic Park on Wednesday night.
Home fans produced the banner of a figure in a paramilitary-style outfit, held aloft alongside another banner featuring manager Brendan Rodgers.
UEFA rules prohibit "any message that is not fit for a sports event, particularly messages that are of a political, ideological, religious, offensive or provocative nature".
The club criticised the behaviour of the "small minority" of fans responsible.
Any support for a paramilitary or proscribed terrorist organisation has no place at Celtic Park.
The Club has been consistent in condemning such conduct on the very few occasions in the past when it has occurred at Celtic Park.
It is unfortunate that such a small minority of the crowd at Celtic Park last night behaved in such a way.
We know that the Celtic support will join us in condemning such behaviour.
Closures
Celtic have now gone a step further. The club confirmed they will close the safe standing section of the ground for the next two matches after "serious incidents of unsafe behaviour".
The decision, which has been taken amid serious safety concerns and after discussion with the police, follows events at the matches against Hearts in May and Linfield on Wednesday night.
On both occasions, flares were set off in the safe standing section of the stadium, which the club described as "incredibly irresponsible" and something which could have had "tragic consequences".
While the initial ban is for two games, it does not sound great for the prospects going forward.
Safety of all supporters at Celtic Park is of paramount importance to the Club. The safe operation of the safe standing area at Celtic Park requires effective communication and engagement with the supporters in that area. Unfortunately, due to the events at the Hearts and Linfield matches, the Club is not satisfied that the Green Brigade section can be operated safely at this time.
The 900 season ticket holders affected have been contacted about the steps to follow if attending upcoming games.
