Allan McGregor in livid Rangers rant at 'state' of referees as Neil Lennon tells Ibrox hero 'you're on one'

Rangers legend Allan McGregor has slammed the "state" of referees in Scotland following a controversial call during the Scottish Cup final clash with Celtic.

The former No.1 was involved in a prickly spat with Neil Lennon after referee Nick Walsh opted not to penalise Cameron Carter-Vickers for a first-half foul on Cyriel Dessers in the penalty box - that led to the Rangers striker limping off at half-time. The man in the middle Walsh was in for a busy afternoon as he was sent to the monitor by John Beaton to chop off a goal from Abdallah Sima - which looked to be the opener. The whistler opted to award a free-kick to Joe Hart after what appeared to be a push from Nicolas Raskin in the build-up as the corner was fired in towards the outing Hoops No1.

Adam Idah then popped up in the final moments of the game to punish Rangers as he followed in on an effort that was pushed out by Jack Butland and fired under the Light Blues No1 to send the green and white half of Mount Florida wild. It proved the winning moment for Brendan Rodgers' troops who secured a double having already bagged the Scottish Premiership title.

It was party time for Idah and his team-mates, but the studio pundits were only getting started with their analysis. However, the row between the former Old Firm stars was already rumbling before the full-time whistle. Liam Scales had appeared to give away a free-kick as he barged Dujon Sterling off the ball. Analysing the incident at half-time, Lennon said: "Yeah, it's a clear free-kick. He has pushed him in the back and taken him out at the legs. I don't know why he hasn't given that one against Liam Scales. I think he is fortunate to get away with that."

McGregor answered: "It's mind boggling. It doesn't surprise me with the state of these referees to be fair..." Lennon attempted to defuse the rant stating: "Oh, he is on one now." Undeterred McGregor went on: "Oh yeah, I'm on one. The linesman is about 15 yards away. He has got two hands on his back, what is he looking at? It doesn't surprise me to be fair."

A heavy challenge by Carter-Vickers on Dessers was then flagged on Premier Sports. Lennon gave his take as he said: "It's a good block from O'Riley. It's a good follow up from Carter-Vickers - it's a really strong challenge, but it's clean. There is no hint of a penalty there whatsoever. It's a good reaction from Carter-Vickers, and Dessers goes over. It's not a penalty, no way."

McGregor wasn't having any of it saying: "I still think it's a big naughty..." Lennon clapped back: "There is no touch on the follow through..." McGregor continued: 'I get that. My wee pal in her room at Hampden once told me when I asked her if to endanger the opponent you need to actually touch the person, and she said no." And nodding to the yellow card Celtic captain Callum McGregor was on at the time, he went on: "He is just lucky his name is not Cameron Carter-Vickers and not Cameron Callum-McGregor or it could have been a red."

The Rangers no goal sparked frustration from Clement as he took a swipe at the officials and VAR for chalking off Abdallah Sima's effort. He cited the earlier push from Scales on Sterling that went unpunished but former referee Bobby Madden was quick to back up his former colleagues. He said: "You see evidence here, it's a push. You can argue all day that the goalkeeper should be stronger but it is a push. Correctly disallowed. No goal."

On the disallowed effort on the hour, the Belgian said: "We had to score at that moment today. But when you score and it’s disallowed in that way, it’s disappointing. Especially when I compare it with the push by Scales on Sterling in the first half. It’s a much bigger push than what happened to Hart.

"I also saw Celtic defenders grabbing my players and having their arms around their necks and waists at that moment. It was a really big call to disallow that goal. It’s their decision. They’re honest but that’s a grey one, not white or black, and he made the decision. But of course, as a manager I’m disappointed.”
