José Mourinho smashed Manchester United's club-record transfer in 2016 to bring Paul Pogba back to Old Trafford.
While there have been moments where the 25-year-old United ace has been criticised for his performances, his current form under caretaker manager Ole Gunnar Solskjær will be enough proof for some fans that he is one of the best midfielders in the world.
Even when he was at the United youth academy, there were many that saw the potential of Pogba.
However, Sir Alex Ferguson allowed him to leave the club for Juventus in 2012 after he turned down a contract.
Okay, some fans would be quick to lambast the legendary United manager for letting him leave and then the Red Devils paying as much money as they did to re-sign him, but it seems like he had his reservations about the World Cup-winning Frenchman.
According to the i newspaper, United 'insiders' revealed that the 77-year-old Scotsman believed that Pogba wasn't mature enough.
Interestingly, the claims are backed up from a number of different viewpoints.
Former United player Darren Fletcher echoed similar sentiments about the former Juventus star when he spent some time coaching the Red Devils reserves.
"I did a spell coaching with the [Manchester United] reserve team, which included Paul Pogba, Jesse Lingard, Ravel Morrison -- a lot of talented players," he told Sky Sports' Monday Night Football in 2018.
"We played [Pogba] a lot higher up the pitch in attacking areas and we felt like he was the one that could go and win us games really.
"A combination of the fact that we felt he had a little bit of ill-discipline in the middle of the park as more of a central midfielder."
In fact, historian Tony Park made an observation that suggested Pogba was fairly inconsistent for the youth team.
"Pogba would have one great game, one average game and one anonymous game," he explained.
"It was why Fergie didn't trust him. When he arrived there were 10 to 15 new players around the scene at the time, all with bigger reputations.
"Ravel Morrison was by far the standout and coaches were giving him lots of attention. Pogba's ability was not in doubt, it was his inconsistency, that's been an issue all his career."
Well, the rest is now history.
Pogba once again rewarded Solskjær's faith in him against Fulham, opening the scoring with a brilliant strike in the first half.
He followed up his performance in the second half after he scored from the spot kick and United secured a 3-0 win at Craven Cottage.
