Celtic fans were left extremely frustrated after failing to qualify for the Champions League.
The Hoops played Kairat Almaty in a two-legged play-off and after 210 minutes of dire goalless football, the Kazakhs prevailed on penalties.
Roy Keane has a soft spot for Celtic having grown up supporting the club in Ireland before going on to play for them in 2006.
The Manchester United legend watched the second leg against Almaty, and footage has now emerged of him laughing about his former colleague Martin O’Neill’s punditry that night.

Keane laughs at O’Neill’s Kairat Almaty vs Celtic punditry
Celtic legend O’Neill was a pundit for Amazon Prime and when it was confirmed the game would go to extra-time, Keane was in hysterics.
Speaking on The Overlap’s behind-the-scenes video uploaded on YouTube, Keane told the little anecdote to the likes of Gary Neville and Jamie Carragher.
Keane asked: “Did anyone see Celtic last night? Anyone see the Celtic? It went to extra-time and so when it comes back to Martin…
“You know what Martin’s like, the extra-time is killing him! And then he goes on for ages (about it).”

What did O’Neill actually say about Celtic after Kairat loss?
O’Neill was passionate after watching Celtic lose to Kairat on penalties, as the Northern Irishman delivered a potent rant.
He told Amazon Prime: “Celtic, it’s their own fault. They are out of a competition they should be in. They haven’t done enough over the two games.
“There have been little moments. We had the Maeda moment there (one-v-one chance), and that’s absolutely right. He should score the goal.
“But there has never been a sustained six or seven minutes where they put the opposition under that sort of pressure where you thought that they were going to capitulate. It just never happened, not just tonight, but in the previous game.
“I was always concerned about these sorts of matches, and games that you know in November time that you would take quite easily, so that was a worry for a start.
“Then you have everything else on top of that. You have got the expectation. We actually witnessed this. It wasn’t just disappointment about losing to Bayern Munich (last season). It was actually adulation for the team for what they had done.
“So, the first thing you are thinking about is, ‘can we emulate?’ ‘If we can emulate it, can we surpass it?’ And that’s what Celtic Football Club is built on.
“At the start of the programme, you showed 1967, the first British team to win the European Cup. When I stepped into Celtic, not that I expected to win the European Cup, but that’s what you aspire to.”
