Teddy Sheringham does not believe Paul Pogba has what it takes to be considered a Manchester United great.
The midfielder then returned to Old Trafford in 2016 in what was at the time a world record £90million transfer deal.
In his second stint at United, the France international World Cup winner has made 185 appearances, and scored 36 goals.
There has, however, been almost constant speculation surrounding his future, with agent Mino Raiola publicly stating that Pogba wants to leave the club.
The 27-year-old has been left out of the side at times by boss Ole Gunnar Solskjaer this season – though is currently unavailable due to injury.
“It’s just an up and down situation which you don’t normally get from top players – and he’s obviously a top player,” former United striker Sheringham told Goal.
“He’s a quality, talented player, but there is just too many highs and lows for me, and when you are playing for Manchester United, you can’t afford that.
“If he’s a top player, you don’t get left out of the team.
“You might be for a couple of games, just to kick you up the bum and make sure you’re back on track, but for him to be in and out the team, (it raises) question marks all the time, it can’t be right.
“Now, you have to head to Manchester United and say: ‘I want to be a Manchester United great for as long as I’m here and I’m going to prove that to all those doubters’.
“It doesn’t seem that he’s got that in his mentality, he’s just saying: ‘I don’t care what you think!'”

Pogba suffered a thigh injury during the 3-3 draw with Everton on February 6 – and Solskjaer has ruled him out for the remainder of the month at least.
“With Paul, he’s recovering well,” said the manager. “He’s starting the treatment and will still be a few weeks, he won’t be playing in February, that’s for sure.
“So still a few weeks until we see Paul, definitely.”
