Celtic debutant Matt O'Riley described his debut as "crazy" as he strolled his way to a man of the match award against Hearts.
The Tynecastle clash under the lights guaranteed an atmosphere to remember with the visitors emerging 2-1 winners thanks to Reo Hatate's piledriver and a close range finish from Giorgos Giakoumakis.
Liam Boyce halved the deficit in the second half before then missing from the penalty spot after a handball on Nir Bitton.
O'Riley was influential throughout and created chances aplenty to help Celtic keep pace with Rangers at the top of the Premiership, with the gap remaining at four points.
And asked to sum up the atmosphere on Sky Sports, he remarked: "Crazy.
"You know, I've come from mainly in League One where you've got fans. But like this, this is...
"Honestly, I'm not used to it so definitely a good experience for myself in that sense but I'm really happy to get the first game under my belt.
"Hopefully now I can push on really well."
O'Riley reckons Celtic lost their grip on the game in the second half, while the midfielder insists he won't be added to a mounting Hoops injury list despite being taken off towards the end.
"We didn't control the game as well as we should have to be honest," he added.
"“We let them get back into it with quite a sloppy goal. They should have scored another with the pen obviously so in that sense I think we caused our own problems.
“But at the end of the day we still won the game, so that’s the main thing.
“I’m all right! I’m just getting used to it I think.
“I hadn’t played a game in a couple weeks so I’m just… not getting up to speed, but on the 80 minute mark my calf seemed to just seize up.
“It was a tough game so it makes sense.”
