It felt like the whole football world was fascinated by the previous clash between Celtic and Rangers in February.
One of the sport's most famous derbies was the only show in town on a night when Ange Postecoglou 's men roared to the Premiership summit.
But the Old Firm can still draw mammoth interest from across the globe even on a day Juventus and Inter battled in the race for Serie A title, as well as big games in the Premier League and La Liga.
Eyes were transfixed on events at Ibrox as the league leaders won 2-1 to leave Rangers needing a title miracle over the final six games.
And the high drama, which was only spoiled by two separate glass bottle incidents from Rangers supporters, one which injured a Celtic staff member and the other endangered Joe Hart.
Record Sport looks at what has been said about the marquee fixture
Marca (Spain)
Spanish media tipped the big one as one of the can't-miss fixtures in world football this weekend and they were proved right.
"Celtic took victory in the Scottish classic by beating their closest rival, Rangers, by a score of 2-1, thus increasing their advantage over their rival in the race for the league title.
"Tom Rogic and Cameron Carter-Vickers were Celtic's scorers, the same ones who gave the green and white team the somersault since Aaron Ramsey had put Ranges ahead just at minute three.
"The Rangers led by the former Dutch figure Giovani van Bronckhorst collided again and again and again with the defence of their greatest rival who, after scoring the go-ahead goal, decided to withstand the onslaught of his greatest rival, a bet that ended paying off in the race to regain the Scottish Premier League title."

There was a Star Spangled element which had American eyes tuned as they watched Cameron Carter Vickers net the winner.
"Every Old Firm showdown is an occasion in its own right but Sunday's Ibrox clash was monumental, given the implications.
"Not since 2010-11 has the league campaign been as close at this stage; the two great rivals separated by just three points ahead of kickoff with seven games to go.
"To add to the excitement, both sides came into this one on a roll. In the blue corner, the SPFL champions with one defeat in 29. In the Hoops corner, a Celtic side with 21 wins and no defeats in their past 24.
"There was no escaping Carter-Vickers, though. As half-time creeped closer, the on-loan Tottenham defender found space inside the area and his left-foot strike was too hot for McGregor, as the ball flashed between his desperate legs.
"The second half settled into a pattern quickly; the home side displaying boisterous endeavour and the visitors repelling attacks while playing with the air of calm authority in the face of Rangers' attempts to retrieve a result. Rogic, imperious all day, was withdrawn along with Hatate for Matt O'Riley and Nir Bitton on the hour mark as the game became scrappy, with neither side calm enough in possession.
"Hart made then made a big stop from Fashion Sakala to his left as the home fans' cries got even more desperate, and as the sands of time slipped through Rangers' fingers, the small corner in Ibrox housing the 700 travelling faithful began to dream of winning their trophy back."
Guardian (London)
Jonathan Liew was at Ibrox to witness Celtic earn a signature result and leave 50,000 expectant Ibrox supporters crestfallen.
"At full time a deathly hush seemed to descend over Ibrox: the realisation that a season’s efforts had come to nothing, that the title they spent a decade craving and coveting and finally claiming last year has now all but slipped from their grasp.
"For, after a performance of extraordinary maturity and resilience in the most hostile of settings, Celtic are six points clear in the Scottish Premiership. Their 700 fans, whooping and celebrating in their cramped little corner of Ibrox, knew as well as anyone that the game is up."
DAZN (Japan)
Japanese football expert Dan Orlowitz has translated the best reactions form commentators who were broadcasting the contest in the Land of the Rising Sun.
And Celtic earned some heady praise with manager Ange Postecoglou's impact saluted.
They said: "Seeing Rogic's performance made me think how lucky Japan was that he missed the WCQ.
"Were there always this few seats for away fans at the Old Firm? This is like a Spanish derby.
"It looks like Postecoglou's attacking style has permeated into the team.
"Maeda was the last piece they needed to complete the system."
"Rangers fans' hopes for a win were shattered like those glass bottles."
