Barry Ferguson made history as Rangers snatched a dramatic Old Firm victory over bitter rivals Celtic.
His side edged a five-goal thriller at Celtic Park on Sunday thanks to Hamza Igamane’s 88th minute winner.
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 caretaker boss 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.
Meanwhile, the celebrations of the Rangers players on the pitch caused a furious reaction from the home supporters.
As Vaclav Cerny sprinted down the touchline towards the away supporters, he could be seen spraying a drinks bottle into the crowd.
The home supporters splashed by the liquid could be seen furiously reacting in the stands.
Their anger at the incident remained as Cerny returned to the dugout to take his place on the bench, having been replaced by Igamane just five minutes before the goal.
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.
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.
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.
