Managerial changes added further intrigue to the encounter, with Martin O’Neill in charge of Celtic and Danny Rohl recently taking charge of Rangers.

Celtic had the ball in the net just before the 20-minute mark when an attempted clearance came off a Rangers player and ended up in the net, but following a VAR review it was ruled out for offside in the build-up.

After guiding Celtic past Rangers, Martin O'Neill concedes he'd "secretly love" to lead the team in next month's final.

The VAR image showing the incredibly tight offside call to disallow an opening goal for Celtic against Rangers has been released. Martin O'Neill's side looked to have taken the lead after 19 minutes when Nasser Djiga's clearance bounced off of Nico Raskin and into the Rangers net.

After an energetic start, Celtic initially took the lead thanks to an own goal, as Nasser Djiga knocked the ball off Nico Raskin. However, after a short delay, Celtic celebrations would be silenced as VAR overturned the goal, ruling that Daizen Maeda had been offside in the build-up. An extremely tight decision, but the Celts pushed on.
