Brian Wilson has defended Celtic supporters and pushed back against criticism from Scotland’s top police officer following the chaotic scenes at Ibrox on Sunday.

The interim Celtic chairman also revealed that the banned Green Brigade could return to Celtic Park if they agree to specific safety conditions.

Chief Constable Jo Farrell earlier criticised both Celtic and Rangers for not immediately condemning the disorder that erupted after Celtic defeated Rangers on penalties, with supporters spilling onto the pitch.

Rangers eventually responded on Thursday night, promising to identify and punish the fans responsible for the disturbances and condemning those who mocked the Ibrox Disaster.

Wilson, however, stopped short of criticising Celtic supporters who flooded the pitch after Tomas Cvancara converted the winning penalty. Instead, he described the reaction as an emotional celebration similar to scenes seen elsewhere in Scottish football.

Speaking to Celtic TV in an eight-minute interview, Wilson said he was disappointed by Farrell’s remarks, stressing that Celtic maintains a close working relationship with Police Scotland.

He explained that the club takes action when there is clear evidence of unacceptable behaviour but insisted that simply issuing public condemnations does little to solve long-standing issues.

Wilson argued that what happened after the decisive penalty was primarily a moment of celebration from fans and noted that pitch invasions have occurred several times across Scottish football this season without attracting widespread condemnation.

He welcomed the Scottish FA’s decision to launch a full investigation and said it would be important to assess the evidence before drawing conclusions.

“If there is proof of violence or threats of violence, then of course I will condemn that,” he said, adding that it is important to avoid creating a “false narrative” before the facts are established.

Wilson also revealed that Celtic recently met with supporter groups who raised concerns about the policing operation at Ibrox. Fans complained about being funnelled through tight security checkpoints near the Broomloan Stand, creating what they described as dangerous bottlenecks.

He said those concerns would also form part of the SFA investigation and insisted the club preferred addressing such issues through discussions with authorities rather than public statements.

According to Wilson, experienced supporters who regularly attend Old Firm matches raised genuine concerns about safety, which the club takes seriously.

Meanwhile, the Celtic chairman confirmed the club is attempting to facilitate the return of the Green Brigade to Celtic Park.

Celtic said it had already met with Glasgow City Council’s Safety Advisory Group in an effort to allow the ultras group back into the stadium ahead of the upcoming match against Motherwell.

However, the council highlighted several outstanding concerns, particularly around supporters agreeing to stadium rules and the safety and stewarding arrangements within the section.

Club officials have since met Green Brigade representatives and outlined the requirements needed to address those issues.

Celtic stated that if the group agrees to cooperate with the safety and security measures demanded by Police Scotland and the Safety Advisory Group, the club would support their return to Celtic Park.

The club added that the requirements have been communicated to the Green Brigade and they are now awaiting a response.
