Speaking on talkSPORT radio, former Arsenal midfielder Ray Parlour said: “You go back to Sir Alex Ferguson when he let Paul Pogba go, he wasn’t his sort of player — there’s a reason why he let him go.
“Sir Alex must have looked at him and said his dedication isn’t right or something’s wrong, that’s why he let him go. He’s come back to the club and maybe he’s still the same. Sometimes you don’t change.
“Over the years I’ve been watching Pogba play and I’m thinking, ‘come on, liven up a bit’, you know? As a player you’ve got to perform every week, you’ve got to put the effort in every week.
“You haven’t seen that from Pogba in a Manchester United shirt. Sometimes it just doesn’t work out as a player, it’s a lot of money to spend, he was a big signing for Man United.”
Pogba first left Man United back in 2012 with Sir Alex publicly blaming the Frenchman’s controversial agent Mino Raiola for influencing the player’s decision.
The midfielder will be leaving Old Trafford for the second time at the end of the month and he’s expected to once again sign for Juventus on a free transfer.
