"There was always a chance it was going to come to this," Gary Neville said, recently reflecting on the dark day Manchester United's stars gathered with Sir Alex Ferguson and his staff to watch Roy Keane's "destroyed" interview in 2005.
It was an attempt to clear the air.
It didn't work.
"This moment... was sort of coming," Neville admits, referring to a seemingly inevitable confrontation between his captain and his manager that proved fatal for the relationship between two men who are, at the end of the day, mirrors of one another.
Stubborn. Hungry. Born winners.
"That meeting was horrific, by the way... it was horrific, let's be clear. It's not funny. Honestly, it was horrific. You could not say anything.
"You thought 'oh for f***s sake.
"You knew that was it."
When Manchester United are losing Keane still cannot hide his frustration, firing broadsides at under-performing players from the Sky Sports studio.
The angry Keane has toned down a bit recently, mostly thanks to United's form, and while his knives have been sharpened for the players he's tended to fight the corner of the manager.
A year ago he said Ole Gunnar Solskjaer needed time, just as David Moyes, Louis van Gaal and Jose Mourinho all needed time before him.
Not long ago Keane was accusing this group of players of coming close to getting Solskjaer sacked, just as they did with Mourinho.
The former midfielder said he'd have "lynched" David de Gea after a mistake at Everton last March and said he was "staggered" by Harry Maguire's defending in the draw at Tottenham in June, the same day he said he was "sick to death of this goalkeeper".
"I'm disgusted with it. Maguire, De Gea... you should hang your heads in shame."
Keane's caustic tongue is nothing new, and amid all the barbs over the past two years Solskjaer has rarely responded in his press conferences.
But then the United manager knows this is nothing new from the Irishman, as does the latest addition to the coaching staff, Darren Fletcher.
The only difference now is that Keane is at least throwing grenades as an interested - and clearly passionate - observer. The first insight into his no-nonsense punditry came just over 15 years ago when he was captain of the side.
The lines were just as brutal, only then they were directed at teammates.
Keane was playing the pundit on MUTV as he analysed United's 4-1 defeat to Middlesbrough in late October 2005 and he pulled no punches.
Fletcher was one of the players taken apart. That the dissection of the disastrous defeat came on Halloween was a fitting omen for Keane's punditry career. There truly are few things scarier in football than having an off day pulled apart by Roy Keane.
Rio Ferdinand, John O'Shea, Alan Smith, Kieran Richardson and Edwin van der Sar were also targeted by Keane and while the footage was never aired and has since been destroyed - which says a lot for Ferguson's grip of power at United - there are quotes all over the internet that don't make for pretty reading.
Keane had already announced he planned to leave the club at the end of the season, when he'd have been a few months short of his 35th birthday, but watching the club he'd captained to glory capitulate at the Riverside Stadium was the final straw.
Had the footage ever seen the light of day it's fair to say Keane's views would probably have been greeted with approval amongst most of the fanbase.
United had finished third in successive seasons, 15 points adrift of Arsenal in 2003/04 and 18 behind Chelsea in 2004/05. Add in the fallout from the Glazer takeover, which had gone through six months earlier, and the mood around Old Trafford was toxic. Keane was saying what the fans were thinking.
Four days after the defeat at Middlesbrough United were beaten by Lille in the Champions League and some of the players were barracked on another dreadful night.
The day after Keane was sacked United's away day fans sang his name in a win at Charlton. A few days later came a goalless draw at home to Villarreal, when many in the Stretford End sang the former captain's name again at full-time. A statement had been sent. Not that Ferguson ever regretted the decision to tell Keane his days were done.
"It was unbelievable," Ferguson said in his 2013 book My Autobiography of the 'destroyed' tape. "He slaughtered everyone. Darren Fletcher got it, Alan Smith. Van der Sar. Roy was taking them all down. I told him 'What you did in that interview was a disgrace, a joke. Criticising your teammates and wanting that to go out.' Roy’s suggestion was that we should show the video to the players and let them decide.
"The nature of the man you can expect that, that is the personality he has. But the reason was I had to explain what happened. It happened so quickly. He criticised his teammates. We could not release that video. It ended up with two young players being booed in Paris [in the game against Lille] on the Wednesday."
Keane has spoken of two regrets from that time: apologising and that the show was never aired.
Speaking at an event in Limerick in 2017 he said: “I wished they played this video, it is propaganda, ‘we had to destroy it’. How do you even destroy a video? I left with my head held up high, I was fine with my actions, I always felt my intentions were to do the best for Man United.”
In his book The Second Half he said he wished he hadn't apologised.
He wrote: "I just wanted to do the right thing. I was apologising for what had happened – that it had happened. But I wasn’t apologising for my behaviour or stance. There’s a difference – I had nothing to apologise for.”
Ferguson once said of Keane that he has "the most savage tongue" and when the bile was directed at his teammates that was too much for the manager, who clearly felt the dressing room omerta had been breached.
Supporters who sided with Keane felt it was Ferguson's responsibility to be telling players they were under-performing, but the manager may also have felt that Keane's attacks were an attempt to erode his own powers, which were so strong that earlier in that 2005/06 season he'd boycotted MUTV himself because a presenter said United should play a 4-4-2.
Ferguson said in his book that United had "11 years out of Roy" - he was actually at the club for 12 years - and the true surprise is probably that two characters with such fiery and stubborn personalities co-existed in relative harmony for so long.
Keane may have felt Ferguson was a fading force when he left the club and that United were drifting, but as was so often the case, it was the manager who would be proved right.
By the end of the 2005/06 season United had climbed to second. They would win the league the season after, the first of five titles post-Keane and the dust would settle for Ferguson. His rockiest season since 1989/90 was merely the prelude to more glory.
Keane may well think he was right about some of the players he chastised back in 2005. Fletcher was on the receiving end - "I can't understand why people in Scotland rave about Darren Fletcher" - but speaking to the UTD podcast last year Fletcher defended his former midfield partner over the interview.
Manchester United beat Fulham 2-1 thanks to goals from Edinson Cavani and Paul Pogba.
Pogba once again turned in a high-class performance as Ole Gunnar Solskjaer's side reclaimed top spot in the Premier League. Now United turn their attention to another clash with rivals Liverpool, this time in the FA Cup fourth round.

Fletcher said a lot of the criticism relating to one game was "misconstrued" as a wider-ranging attack. He also looks back on Keane's own words against him and holds no bitterness, even if he can accept why Ferguson would have had a problem with the interview.
"It was Roy Keane challenging me as Manchester United captain and it was something I was used to in the dressing room," he said. "The long and short of it is that I knew Roy Keane liked me and that was his way of showing he liked me, because he knew I was capable of more and wanted to challenge me. He would say 'yes, I was little bit harsh there on Fletch but it's because I like him and want him to do well'. So, for me, it was no problem at all.
"It is something that hung around me for a long time, the fact that Roy Keane didn't like you and didn't rate you. But, for me, it was the complete opposite. I knew that Roy Keane really liked me.
"He challenged me and was hard on me, 100 per cent, but that was his way of making me a Manchester United player, manning up. The personality and the leader that I became was off the back of that grounding and that schooling.”
Whether Keane played a part in the making of Fletcher we will never know, but the United coach credits his former captain with toughening him up.
When Solskjaer confirmed Fletcher's return to the club earlier this month he said he had the "United DNA and he knows exactly what it takes to be a Manchester United player."
At such a demanding club, criticism comes with the territory. Fletcher understood that and grew from it. The current crop who have been on the receiving end of Keane's razor-sharp tongue also understand it.
One of the fascinating aspects of Keane's punditry since Solskjaer's arrival has been his backing for the manager. While the players have often got both barrels, the manager never has. But maybe Solskjaer's cameo in the 2005 drama explains it. As Keane himself explained, loyalty means a lot.
A team meeting to clear the air was called, and the players were shown Keane's first taste of life in the pundit's chair.
After the viewing, Van der Sar suggested he could have used a "different tone", advice that evidently still falls on deaf ears.
“Edwin, why don’t you shut the f*** up? You’ve been at this club for two minutes and you've done more interviews than I’ve done in my 12 years. It was MUTV – I had to do it," Keane said.
Much more was said - none of it pleasant. The air had not been cleared.
Keane stormed out, only to be followed by Solskjaer and Scholes.
"All the players started talking and Ole and Paul Scholes said they were leaving because they didn’t want to talk about me when I wasn’t there," Keane recalled. "I love that – they showed me a bit of loyalty.
"When Ole got up to leave, he was told by the manager, ‘don’t you follow him’ in no uncertain terms. According to Ole, Carlos Queiroz called him into his office the next morning and told him to apologise to the manager for leaving the room or he’d be sacked.”
Now, more than 15 years on, Solskjaer is the man in charge. Thankfully MUTV no longer ask anyone to 'Play the Pundit', although Keane's views are as forthright as they ever were.
