Steven McLean was the referee tasked with the unenviable duty of controlling the derby contest between Celtic and Rangers.
The experienced whistler, 43, was assisted by Graeme Stewart and Dougie Potter running the line with John Beaton as VAR, assisted by Sean Carr.
McLean can be pleased with his afternoon's work as he refereed the fixture exactly how it should be handled.
The biggest compliment you could pay to a referee would be them being largely anonymous in big matches, McLean was close to that.
It threatened to be a busy afternoon with the first foul awarded after just 15 seconds of play as Reo Hatate fouled Mohamed Diomande in the final third, but McLean wasn't overly worked.
There were no difficult calls to be made on Rangers' opener with a James Tavernier corner flicked home by leaping Nico Raskin at the front post. So simple was the award, there was no VAR delay.
McLean was perhaps overly lenient for some, but in exercising caution in distributing bookings, the official allowed the match to be played in the spirit intended.
Connor Barron and Nico Raskin could have been booked early in the match but McLean overlooked a series of small fouls with Daizen Maeda also not penalised for a foul in the first period.
It was the sensible refereeing Scottish football fans have been crying out for.

McLean did reach into his pocket for a yellow card in the 34th minute as Dujon Sterling fouled Jota. Again, it was the right call with Sterling taking one for the team to stop a promising attack.
Rangers' second was passed without issue either as Diomande was clearly onside with no contentious factors in the attacking phase of play to cause any VAR intervention.
Barry Ferguson was booked in the 41st minute for his reaction to a daft rammy before the break. McLean was quick to separate the players and get the game back moving again without any bookings for those on the pitch.
McLean did, though, jog over the issue a yellow to Ferguson - perhaps advised it was necessary by the fourth official.
As with both Rangers goals, there were no issues for either of Celtic's in the second half. Maeda's header was clearly onside and there were no complaints for a foul or anything in the build up.
Hatate's slick finish was a similar situation. A smart ball through allowed the Japanese midfielder to stroke home - offside would have been the only possible reason for it to be chopped off but he was also clearly onside.
Robin Propper was next in the book for a silly challenge on Maeda. The defender got his timing all wrong and it was an obvious cautionable offence but nothing more.
Ianis Hagi joined his team-mates in receiving a yellow card after 77 minutes as a free-kick smashed off him standing just yards away. Hagi was delaying the restart but it was perhaps harsh to show the yellow when the free-kick would not likely have been hit in that direction if he were not standing there.
Hamza Igamane's winner was another easy moment for McLean. A long ball over the top was simply missed by Cameron Carter-Vickers before Alistair Johnston's slip allowed Igamae to hammer into the top corner.
So straight forward was McLean's handling of the match, VAR did not once even threaten to intervene - a real positive for Willie Collum and the Scottish FA after failings in recent months.
