Danny Rohl hinted at frustration over two major decisions after Rangers lost 3-1 at Celtic Park, but neither incident looked anywhere near as controversial as some were trying to make out afterwards.

The Rangers manager pointed towards Yang Hyun-jun’s equaliser and Alistair Johnston’s second-half challenge on Mikey Moore while discussing the defeat. Social media quickly filled with complaints from the away side over Benjamin Nygren’s positioning during the first Celtic goal and whether Johnston should have seen more than a yellow card.

But looking back at both moments, the arguments feel weak.

Yang’s goal came from quick movement inside the box after Luke McCowan and Arne Engels opened Rangers up down the right side. Nygren was standing near Jack Butland when Engels squared the ball across goal, but the Rangers goalkeeper never looked close to saving the finish.

Yang connected cleanly from close range and Butland was already beaten by the pace and angle of the pass before the shot arrived. Nygren did not block the goalkeeper’s movement and there was no reaction from Butland suggesting his sightline had been affected badly enough to stop him making a save.

The officials checked the goal and allowed it to stand quickly.

The Johnston challenge also looked fairly straightforward in real time. The Celtic full-back caught Moore late during a heated spell midway through the second half and referee Nick Walsh immediately produced a yellow card.

It was clumsy. No doubt about that.

But Johnston was not out of control and there was no lunge with excessive force. Moore got up quickly afterwards and the game moved on without lengthy treatment or a VAR review recommending stronger punishment.

Rohl tried to avoid directly criticising the officials after full-time.

He said: (Sky Sports), “I never look for excuses, but what I heard, maybe there is an offside, maybe there is a red card, but maybe there is a decision-making on the pitch, I’m not the manager to attack in public the refs.”

The bigger issue for Rangers was probably what happened after Celtic equalised.

Once the home side settled into the game, Rangers struggled badly to cope with the pressure. Callum McGregor started dictating possession, Kieran Tierney drove Celtic forward repeatedly and Daizen Maeda’s movement became impossible to contain.

By the final half hour Rangers were pinned deep for long spells and looked exhausted trying to chase the ball.

That decided the match far more than any refereeing call.
