Celtic fans held back from dugout by police as Rangers manager achieves 34-year Old Firm first

Celtic fans had to be held back by police after Rangers’ dramatic late winner in the Old Firm derby.
The visitors snatched all three points from Celtic Park after Hamza Igamane came off the bench to score in the 88th minute.
In the chaotic celebrations, several Rangers substitutes raced down the touchline to join their jubilant team-mates.
Amongst them was winger Vaclav Cerny, who had been replaced by Igamane just five minutes earlier.
As the Czech international ran past the home fans, he could be seen spraying a drinks bottle into the crowd, prompting a furious reaction in the stands.
Their anger over the incident remained as Cerny and his team-mates returned to the Rangers dugout.
Footage of the dugout showed a row of police officers keeping back the livid Celtic fans.
Several supporters were shown on Sky Sports' coverage arguing with the officers as they pointed towards the Rangers bench.
Meanwhile, Cerny could be seen with a wry smile on his face as the match edge closer to its conclusion.
On the pitch, meanwhile, Rangers had raced into a two-goal lead by half-time thanks to goals from Nicolas Raskin and Mohamed Diomande.
However, Daizen Maida and Reo Hatate both scored for the hosts to level the score heading into the closing stages.
There was still time for a winner, though, as Igamane latched onto Jack Butland's long ball before finding the top corner.
Butland's pass was his first career assist and helped give Ferguson a piece of Old Firm history.
The Rangers legend becomes their first manager to win his first match at Celtic Park since Walter Smith in 1991.
Ferguson was put in temporary charge last month following Philippe Clement's sacking.
Interim boss Ferguson was asked about the incident after the game.
Asked if he seen what happened after the goal Ferguson said: "No, I was concentrating on making sure that I come up with a formation to see the game out.
"I'm just glad I wasn't involved. I've got to try and focus on my team. I don't know how many minutes were left.
"Was there seven or eight minutes? Then I need to make sure that we're drilled into the information just to see the game out and obviously come away with three points."
The 27-year-old Czech international joined Rangers on loan from Wolfsburg in the summer.
He has since faced Celtic four times across both the league and Scottish League Cup.
Rangers legend, and talkSPORT host, Ally McCoist absolutely loved what Cerny did and joked he should get a knighthood.
“I think he's definitely recharged it. Because I think two minutes prior to it, he's actually gone around four or five bottles and topped one up.
“He specifically got that guy. Something happened there.
“I watched him about 411 times. Honestly, I could not believe it.
“The best thing is, he gets back into the dugout and he's waving.”
When asked if something is going to happen, McCoist said: “I think so. It's absolutely a knighthood, I would have thought.
“I like the sound of that. Sir Vaclav Cerny. It's got a nice ring to it, hasn't it?”
Despite Sunday's defeat, Celtic remain on course for their 55th title and a 13th crown in 14 seasons.
Brendan Rodgers' side are 13 points clear with just eight matches remaining this season.
The two sides will meet for a final time in the league after the top flight splits in half after every club has played 33 matches.
