Ryan Stevenson has criticised Celtic staff after accusing them of provoking the Hearts bench during a tense title finale.
Derek McInnes’ side were left heartbroken when Daizen Maeda scored in the 87th minute to trigger wild celebrations following a prolonged VAR review.
Hundreds of supporters then spilled onto the pitch after Callum Osmand added a third with the last kick of the game, forcing police to escort the stunned Jambos down the tunnel for their safety.
Several reports have since claimed that players and staff were “assaulted” during the pitch invasion, with footage appearing to show multiple heated clashes involving supporters.
Tynecastle officials issued a strongly worded statement on Saturday night calling for the “strongest action possible” from authorities, claiming they were forced to leave Celtic Park due to a “menacing and threatening atmosphere inside the stadium”.
While Police Scotland are expected to investigate the disorder, Stevenson also pointed the finger at unnamed members of the Celtic bench over their behaviour after Maeda’s dramatic late goal.
Sky Sports cameras showed unused Hearts substitute Sabah Kerjota reacting furiously towards the home dugout, while McInnes was also seen calming assistant Alan Archibald during the incident.
In an interview with talkSPORT, Record Sport columnist Stevenson condemned the chaotic ending and said: “Listen, I think everyone is okay. Having spoken to a few of them, there have been altercations between fans and players.
“Regardless of the situation, there’s no way a player can be at his work and feel threatened. The other side of that is, there are families watching on TV.
Their families, their kids, their wives, partners, mums, dads… there are family members at the game, and the last thing we want to see is fans on pitches striking players.
“What also has to be said is some of the Celtic bench as well, I think when the second goal went in or was awarded, going straight over into the Hearts dugout as well.
“That has to be stopped. If that’s how the bench is acting, then the fans see that… it just heightens everything.
“There’s a responsibility between everyone. What I don’t want to get away from – and the exact same from a Celtic side – is what has been an absolutely tremendous season. It’s been absolutely amazing.”
However, Stevenson also commended the majority of Celtic supporters for jeering the pitch invaders and highlighted one fan who tried to protect Hearts captain Lawrence Shankland from hostile confrontations.
He said: “I know Hearts fans will be absolutely gutted, but I think in general, there’s that sense of pride towards the players.
“What I have to say as well, you can clearly hear in the microphones, 59,500 fans were booing the fans going on the pitch from the Celtic side. That also has to be said.
“There was one fan that I saw who was around Lawrence Shankland, who was a Celtic fan, trying to wave other fans away.
“But, we have a responsibility as human beings that we can’t act this way. These are guys who are going to their work and trying their hardest.
What a spectacle for Celtic to get the second goal in 87 minutes. But for it to end the way it did was pretty sad.
