When Memphis Depay arrived at Old Trafford, he was supposed to signify the club's progression from the frustrating, albeit brief, David Moyes reign.
The glory days of Sir Alex Ferguson and co. would come roaring back with some young and exciting signings, right?
Well, not quite. Things didn't really work out that way for poor old Memphis and he was sold to Lyon last January for a reported £16-17 million, just two years after arriving at Old Trafford for £25 million.
So what happened? When Memphis arrived, he was the odds-on favourite to win the PFA Young Player of the Year, even ahead of the established starlets like Philippe Coutinho and Raheem Sterling.
Just two years later - including an exciting start complete with an impressive Champions League brace - he was packing his bags.
Since moving to Lyon, the Dutch international has provided plenty of highlights in games and training to display the quality we all knew he had, but he explained to beIN Sport why he believes former boss Jose Mourinho let him go.
“I have no bitterness towards Mourinho,” he said. “I did what I had to do in training. Of course, I didn't understand his choices, but he was the boss. I had to accept those choices. I think I was not good enough for him. But it's okay, I'm showing my quality here.
“I'll be back to the top and we'll see what will happen.
“Leaving Manchester United? That was not complicated. I'm young, I need to play.
“When I think about the last time I played a whole 90 minutes before coming here, it was a year ago. It's incredible.”
Quality wise, Memphis has to be good enough for Mourinho, and anyone else for that matter.
But, perhaps, the same way that Juan Mata and Kevin de Bruyne found their time at Chelsea numbered, Memphis didn't work hard enough at both ends of the pitch to satisfy the Special One.
United inserted a buy-back clause in the deal that sent the winger to Lyon, so the club knows he could still end up a top player in the future.
Will Mourinho ever take him back though?
