Rangers say “all parties must be prepared to have their actions and decision-making subjected to proper scrutiny”, with Celtic referencing “serious concerns” raised by supporters about pre-match access arrangements.
The Ibrox club have called for the review to be “thorough and wide-ranging” and to “include the broader context” around the match, from initial decisions on ticket allocation through to the post-match incidents.
Their statement adds: “The disorder that occurred on Sunday was unacceptable and we condemn it unequivocally. Safety must always come first in football, for supporters, players and everyone working in and around the game.
“There are now a number of serious issues which require proper examination. For that reason, we agree that there should be a fully independent review into the events surrounding the match.”
Rangers have vowed to represent the club and their supporters “robustly” but say they will take action – “including the potential withdrawal of ticketing privileges and stadium bans” – against anyone identified and convicted.
The club also say they are “appalled” to discover graffiti mocking the Ibrox disaster, which claimed the lives of 66 supporters in January 1971.
They add: “To desecrate their memory is vile. It is cowardly. It is shameful. This is not football rivalry and it is not banter. It is the abuse of a tragedy that claimed 66 lives.”
Meanwhile, Celtic say they are awaiting a response from the Green Brigade regarding safety and security measures – as required by the police and Glasgow City Council’s Safety Advisory Group – to allow the club “to advocate re-entry” of the banned fan group to Celtic Park.
