Roy Keane offered his immediate reaction to Celtic's 1-0 loss to Rangers as he passed by a live recording of a Celtic fan media show outside Parkhead.
The Manchester United legend was inside Celtic Park to watch the derby match as he was picked up on Sky Sports cameras looking on.
And after the match, the former Celtic midfielder walked right past a live video being shot by Celtic AM in Glasgow.
During the recording, host Hamish Carton said: "There's Roy Keane. Roy Keane is just walking by.
"Alright Roy, you hero. Any thoughts, Roy? Roy Keane has literally just walked by."
Offering his instant reaction, Keane shouted back, "Ups and downs of football".

Quickly, there had been speculation over whether Keane could be a potential management option for Celtic should Martin O'Neill leave his post after a difficult week.
Celtic lost twice to Rangers and were beaten by Ferencvaros at home in the Europa League in the space of the last seven days.
And O'Neill admitted he would take time to consider his future at Celtic.
He said: “I will reflect on the games.
“I’ll obviously speak to the board. And you never know, they may want to speak to me. But yeah, I’ll see. I’ve got some time to do that.
“I will have a look, try and get a couple of days away and see how it goes.”
Asked what would happen if he reflected and then decided he could not improve the team, O’Neill replied: “By that time, I will promise you, I’ll let you know.
“I don’t know. I’ll have a look.”
