Carl Starfelt's uncle lapped up a derby night for the ages before returning home with a souvenir to treasure.
The Celtic defender and Swedish international had relatives in the Parkhead stand to take in Wednesday night's thumping victory over Rangers.
And one returned home with Joe Hart 's match-worn shirt in tow for his son.
Starfelt 's uncle stopped for an impromptu interview with BBC Scotland's The Nine and opened up on an experience he insists he will never forget.
He revealed that his son - also named Carl - has been a huge fan of the former Manchester City keeper for years.
"Carl Starfelt is my sister's son, so I'm the uncle of Carl," he said.
"So it was really good to see him, he's really good and did a great performance. So that was really nice, that was cool.
"(The atmosphere) was insane, we were just behind where the three goals were, we were just behind that goal so we saw all of them.
"It was fantastic. And the crowd were so friendly, and the singing.
"We walked to the stadium, through the bars and just met a lot of great people.
"No! (I won't forget it). I don't think so, no, never.
"I got a signed top from Joe Hart, I got that signed to my son, whose name is also Carl!
"My son has been a goaler, ever since he was a kid and he always looked the Joe Hart videos.
"I asked Carl Starfelt if he could have it signed. It was really nice. This is what he wore yesterday.
"Yeah (my son will be very excited), he doesn't know yet.
"He will be excited, full on."
