Celtic

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.

Former Celtic striker Chris Sutton said of Nygren on Sky Sports: “What a strange player. He can go missing in midfield but comes up with goals.”

Just as well given Daizen Maeda is still looking like a shadow of the player who lit up Scottish football last season, January loan signings Tomas Cvancara and Junior Adamu have yet to fully impress and Kelechi Iheanacho has disappeared from view despite his return from injury.

Nygren is not one of the title winners Tierney talked about in Celtic’s squad, but the 24-year-old Sweden midfielder is doing more than most to make sure he gets that league winners’ medal.

Former Celtic midfielder Scott Allan enthused on BBC Radio Scotland’s Sportsound: “The impact substitutes you’ve seen at the weekend, you’ve seen it again tonight with Benjamin Nygren and James Forrest linking up.

“Lovely tee-up from Forrest and Nygren just finishes – we’ve seen that time and time again and he’s had a real impact in this team.”

Indeed, Nygren has found the net three times and provided one assist in his latest four Premiership games – and his 15 goals are more than any other Celtic player in the league this season.

“I know Nygren gives up certain parts of the game, but what he does do is he gets into the box and gets on the end of things,” Allan said.

“I felt his overall play in the game was really good, played some lovely through balls, always looked like he was going to be a threat round about that 18-yard box and he was the difference again tonight.”

His manager was similary enthusiastic.

“He’s doing something that is the most difficult thing in the game – to score goals -and he’s popped up again with what proved to be the winning goal,” O’Neill said.

“Substitutes in recent weeks have made big contributions to us, so that’s important for us.”
