Paul Scholes says Paul Pogba must raise his game at Manchester United, claiming the midfielder needs to "use his brain" to ensure he becomes one of the game's top players.
Pogba made a sensational return to Old Trafford in 2016, arriving after a successful four-year stint at Juventus for a then-record fee of €105 million (£89m).
The midfielder faced widespread criticism for his early form in the Premier League, however, as he struggled to adapt to life back in the English top flight.
The 25-year-old has steadily found his feet since and was an important figure for Jose Mourinho's United side throughout the 2018-19 campaign, making 25 league appearances despite missing part of the season with a thigh injury.
Pogba ended the domestic season strongly before helping the France national team claim their second ever World Cup trophy, scoring in Les Bleus' 4-2 victory over Croatia in the final.
Despite his success in Russia, however, Scholes has questioned the midfielder's consistency at club level and believes that a settled starting XI at Old Trafford may be the key to helping the Frenchman achieve that.
"Paul needs to find a consistency, I think," Scholes told beIN SPORTS. "You look at his game, he can be brilliant one week and not so good the next week.
"He seems to be a player which you get a performance out of every three to four games. If you're going to win leagues, that's not enough, it's just not enough.
"He needs to become that commanding player he was at Juventus - he was part of a set structure at Juventus, he knew every week which position he was going to play, who he was going to play with, and I don't think that has helped him at United.
"I'd be amazed if the same team has been named twice in a row, or the same formation. There doesn't seem to be a set way of where it's going and that could possibly work against him.
GettyScholes' criticism of Pogba isn't the first time he has questioned him publicly, having previously told the club to sell the midfielder if there was any doubt in his loyalty.
The two were also shunted into the spotlight when Scholes questioned Pogba's attitude following United's 1-0 defeat to West Brom in April.
And while the player-turned-pundit has no doubt about the quality of Pogba, he believes that he still has some way to go before being compared with the best in the game.
"There's no doubt the lad has real quality - he's shown in the World Cup that he can play," Scholes added.
"He's such a strong lad, he's such a fit lad. He can run, he has great technique as well, great ability. But he needs to use his brain a little bit more to become a top footballer."
United kick off the new Premier League season with a home game against 2015-16 title winners Leicester City on August 10.
