Controversy has been the running theme throughout Paul Pogba's time at Manchester United, his original arrival back in 2009 sparked headlines and he continues to do so more than a decade later.
The deep-lying playmaker is thought to be on the cusp of a second Old Trafford exit in a mere matter of months once his current deal expires and he is free to join whoever he sees fit.
The World Cup winner is reported to have plenty of suitors and has made little secret of his desire to join certain European giants at some stage of his career.
However, anyone who does acquire the Frenchman's signature may want to look at the acrimonious circumstances that marred his first departure from united and likely his second.
HAVE YOUR SAY! Where will Pogba be playing his football next season? Comment below
Pogba's United career began under a cloud after he left Le Havre's youth set-up to join the Red Devils, only for the French club to try and intervene by claiming it had a "non-solicitation agreement" with the player.
That would mean the club could automatically sign him to a certain contract once he hit the required age, the whole saga saw Le Havre release an official statement criticising United only for the Premier League giants to threaten legal action.
After Pogba had denied United had offered him extra money and a house, he was free to get his head down and try to achieve what so many fail to do in reaching the senior side at Old Trafford.
His first call-up would come two years later when then-manager Sir Alex Ferguson selected him in the match-day squad for an FA Cup clash at home to Crawley Town.
He spent the rest of the 2010/11 season with the Under-18 side before Pogba's career really generated paper talk the following campaign.
The rise to the first-team
Pogba's performances in the academy set-up led to plenty of pundits and fans alike tipping him as United's next great midfield hope.
So much so, that at the start of the 2011/12 campaign Ferguson revealed that that then-teenage midfielder would definitely be a part of the first-team fold that season.
"I mean if we hold Pogba back, what's going to happen? He's going to leave," United's iconic former boss told reporters at the time.
"You know, in a couple of years' time when his contract is going to finish. So we have to give him the opportunity to see how he can do in the first-team and he's got great ability."
On September 19, United made the trip to Elland Road to take on fierce rivals Leeds in the League Cup in a game that resulted in a 3-0 win for the Red Devils.
Prior to kick-off, Ferguson said: I intend to play him [Pogba] against Leeds United" and that is exactly what he did as the young midfielder came off the bench at half-time.
Another appearance duly followed in the next round against Aldershot and things appeared to be going swimmingly for the midfielder, he even made his European debut for the club against Athletic Bilbao as well as Premier League appearances months later.
Yet it was all to come crashing down at the end of the season due to one fateful game against Blackburn.
The departure
Pogba has since revealed the moment he knew he had no choice but to seek a new challenge elsewhere - when he wasn't selected for a Premier League game against Blackburn in the league.
The French international explained honestly to United's official podcast years later why he made the decision to leave in the summer of 2012.
"When I had, like I’ve said before, the chance to play or to come on in this game against Blackburn, that’s when really I had heartbreak," he revealed.
"There was no midfield here – people were injured, [Paul] Scholes wasn’t there, I think he’d retired already and it was before he came back.
"Rafael played in midfield with Ji-sung Park and I didn’t come on in this game. We lost the game. I was on the bench warming up and I thought I would come on and it was a big opportunity for me.
"I didn’t and things happen. The manager has a choice in everything but that day is when I had my heart broken. I told Pat [Evra] that was the chance, I’d been training with him and he’d been talking to me and saying I would have a chance. But that happened, I didn’t play and I was kind of upset."
He subsequently signed for Italian giants Juventus in July of that year, but not before Ferguson let the world know his thoughts on the way in which the two parties split.
The fall-out
"Pogba signed for Juventus a long time ago as far as we're aware. It is disappointing. I don't think he showed us any respect at all, to be honest," the Scot admitted.
"I'm quite happy that if they carry on that way, they're probably better doing it away from us."
His sentiments were echoed by his assistant at the time, Rene Meulensteen, who added: "It is very sad how it goes. It's probably not even the desire of the boy to leave, but he is more motivated by his agent.
"He can earn his transfer. Such a nineteen year-old boy can be led astray. I hope he realizes in time what a great club he's leaving."
Pogba conceded upping sticks to Turin was not an easy decision, but one he deemed necessary.
"So I went to Juventus, which was a hard decision for me. Hard because it was going to another club as well where I was obviously not as one of the starting XI but I’ve got to come as a young player.
"A young, talented player and you have to show yourself again. I went and it was a big challenge for me. I said: 'Go for it, no problem. I want to show I am ready to play for the team'."
And show them he did, the Frenchman became one of the most highly-sought midfielders in world football while at Juve, prompting a United now under the guidance of Jose Mourinho to break transfer records to bring him back in 2016.
United part two
After signing for a world record £89million fee, few would argue against the idea that Pogba has underwhelmed yet again in a United shirt.
There have been faint glimmers of the genius ability many know he possesses, but for a number of reasons the 28-year-old has failed to make the grade.
Speaking last year, United legend Roy Keane issued a scathing assessment on Pogba's second stint at the club.
"As we’ve all discussed many times over the last few years, Paul Pogba’s a talented player, there’s no getting away from that," Keane told Sky Sports.
"But I still feel he hasn’t done enough at Man United. As he mentioned there he fell out with [Jose Mourinho], which was a big problem at the club, but even the last few months, we’re saying he’s been a big influence.
"I think when Man United signed Pogba, it wasn’t to be playing in the Europa League or to be winning the League Cup.
"I think Paul needs a bit of a reminder why he’s playing for Manchester United. They paid big transfer fee, big wages for the likes of him, for United to be competing for league titles and the Champions League."
Instead, Pogba looks likely to walk out of the Old Trafford exit for a second time with no Premier League or Champions League to show for it.
Though his honours list contains an FA Cup and a Europa League, as Keane suggested, those are not the trophies United spend nearly £90m to win.
So as Pogba gears up for what is likely to be the last mega-money move of his career, perhaps the most damning indictment of his second stint in Manchester is that there is no ill-feeling this time - unless the unlikely happens and he does end up at Manchester City.
There is no Ferguson-style figure disappointed with his exit, instead this departure looks likely to be a quiet one out the backdoor to ply his trade for someone like his "dream" club Real Madrid.
