Even Paul Pogba's biggest supporter will concede that the 26-year-old has struggled for consistency at Manchester United.
At times, when given the freedom to express himself in attacking areas, the Frenchman has come out of his shell under Ole Gunnar Solskjaer, showing glimpses of class.
But more often that not he has failed to live up to expectation, especially under Jose Mourinho last season.
Pogba's relationship with Mourinho was far from ideal, both on and off the pitch.
He was criticised by many when footage emerged of a training ground bust up with his former boss.
Back in September, pundit Jamie Carragher commented on the footage and questioned whether he was "worth the hassle."
The former Liverpool defender went on to claim that the idea of seeing a "new Pogba" if Mourinho left was near on impossible:
"In terms of Paul Pogba, I don't know if he's worth the hassle for what he gives on the pitch." he told Sky Sports.
"There's an idea that there's one or the other. So if [Jose] Mourinho goes, you'll see a new Paul Pogba. You won't, I can assure Man United fans, you won't.
"Nobody plays for two years and all of a sudden there's a change of manager and you're a new player.
"We've seen what Paul Pogba is as a player.
"He's not as good as he thinks he is. He's got talent, but his big problem is his understanding of the game.
"It's been a problem since he came, and it hasn't changed now."

Back in February, Carragher did respond to his comments made in September, saying he was wrong about the Frenchman.
But his words have become somewhat relevant again after the latest transfer saga involving the Manchester United midfielder.
"He's been a revelation since OGS came in because he's basically let him play without defending.
"I didn't see this turn around so I have no problem saying I was wrong."
