The atmosphere inside Celtic Park during today’s explosive Old Firm clash between Celtic F.C. and Rangers F.C. was already electric before kick-off, but nobody expected what unfolded in the second half to completely steal the spotlight from the football itself.

Supporters across social media are now calling the thunderous chant from the Celtic faithful “the greatest football chant in the world” after Daizen Maeda’s stunning overhead kick put Celtic firmly in control of the derby.
The noise inside Glasgow’s iconic stadium became deafening. Television microphones struggled to handle the volume as tens of thousands of supporters moved in perfect sync, creating an atmosphere that left even experienced commentators stunned live on air.
For Rangers supporters making the trip across the city, it quickly became a nightmare afternoon. Not only had their side surrendered control of the match after a promising opening, but the relentless wall of sound coming from the stands seemed to completely overwhelm the occasion.
Several away fans on social media admitted they had “never heard anything like it.”
One supporter posted:
“I’ve watched football all over Europe and I genuinely don’t think anything compares to Celtic Park when it gets like this.”
Another wrote:
“The chant after the third goal was terrifying. The whole stadium was bouncing.”
The incredible moment arrived shortly after Maeda’s spectacular bicycle kick made it 3-1 in the second half. The Japanese forward had already silenced Rangers with a clinical finish minutes earlier, but his second goal sent the stadium into absolute chaos.
As the replay flashed across the giant screens, the entire home crowd launched into one of Celtic’s most iconic chants:
“And if you know your history,
It’s enough to make your heart go ohhhhhh…
We don’t care what the animals say,
What the hell do we care?
For we only know that there’s gonna be a show,
And the Glasgow Celtic will be there!”
The sound echoed around the stadium as fans bounced in unison while green-and-white scarves spun wildly across all four stands. Commentators covering the match described the atmosphere as “spine-chilling,” while clips of the chant instantly exploded online, collecting millions of views within hours.
The timing of the chant made the moment even more brutal for Rangers. Danny Röhl’s side had actually started the match brightly and stunned the home crowd early when Mikey Moore fired the visitors ahead. For a brief period, Rangers looked capable of spoiling Celtic’s afternoon.
But once Yang Hyun-jun equalised before halftime, momentum shifted completely.
Then came the second-half storm.
Maeda’s quick-fire double ignited the crowd, and Celtic Park transformed into something resembling a European night under the lights. Every tackle, every pass and every Rangers mistake was met with deafening roars from the stands.
Former players watching the match on television were equally blown away by the support.
One pundit said:
“People talk about atmosphere everywhere else, but this is different. This is football emotion at its absolute peak.”
The chant itself quickly became the main talking point online. Supporters from clubs across Europe began reacting to the viral videos, with many admitting they had goosebumps listening to the sound pouring from the stadium.
Even rival fans reluctantly praised the moment.
One neutral supporter commented:
“You can hate Celtic all you want, but that atmosphere is unmatched.”
Meanwhile, Rangers fans were left furious with their team’s collapse after halftime. Many believed the players struggled mentally once Celtic gained momentum and the stadium erupted.
The derby defeat now leaves Rangers facing major questions heading into the final weeks of the season, while Celtic supporters are dreaming of another title celebration.
But long after the goals are forgotten, this may be remembered as the day Celtic Park produced one of the loudest and most unforgettable football chants the sport has ever heard.
For those inside the stadium, it was more than noise.
It was pure football madness.
