Paul Pogba's time at Manchester United could well be coming to an end.

In the days since Wednesday's 2-0 defeat to Manchester City, reports have suggested the Frenchman is looking to leave and Real Madrid are interested.

It's been three years since he joined United from Juventus for a then world-record fee of £89m but, unfortunately, he hasn't live up to expectation.

Consistently inconsistent probably best summarises his performances in that time.

Rumours of Pogba and Ole Gunnar Solskjaer's relationship 'slowly fading' haven't helped, not to mention the 26-year-old saying that playing for Zinedine Zidane at Real would be a dream.

Solskjaer has a big decision to make and Jamie Carragher reckons if Los Blancos come calling with a £100m bid, United should accept.

In fact, Carragher thinks Pogba just isn't as good as he's made out to be.

"There would be one name on the top of my list [to sell]: Paul Pogba," wrote Carragher for the Telegraph. "The Pogba phenomenon, his status as one of the greatest players of his age, is bewildering. His reputation exceeds his contribution.

"I have heard Pogba described as world class. Being a World Cup winner does not automatically make you that. There is a difference between a world-class talent and a world-class player.

"He does not have the discipline to be a deep, defensive midfielder, nor the influence to be a modern No.8 in the mould of Kevin De Bruyne.

"Even during those more encouraging moments he has shown nothing to suggest you can build a team around him. Juventus didn’t. France didn’t. They found a way to accommodate him because it has never been obvious what his best position is. A succession of managers have tweaked their system on his behalf.

"When United paid a world-record fee for him three seasons ago they were expecting a transformative impact - for Pogba to be a catalyst for success in the same way as Yaya Toure when he joined City, Frank Lampard at Chelsea, and Steven Gerrard at Liverpool.

"We all thought Pogba would be a dynamic, marauding midfielder with the freedom to get forward and drive United to Premier League success and deep into the Champions League.

"In his first season United were sixth. They are still sixth. There are many reasons for that beyond one player. It does not change the fact that during his three years at United, Pogba has not been the midfielder everyone thought he was."

Brutal - but it's hard to argue with Carragher on this one.
