With speculation over his future continuing since then, Pogba has been linked with a move away this month after agent Mino Raiola declared his client’s career at United “over”.
While Mourinho has earned praise from the latest fallout, United’s former forward believes the 57-year-old’s management of the Frenchman was wrong.
Speaking to Stadium Astro after the Manchester derby, Ince said: “Under Mourinho, there were so many problems coming out in the papers.
“That would never happen under Sir Alex Ferguson, never. It’s from day one that this has happened.
“He’s never really adhered himself to the fans, despite joining as a young kid.
“His performances were very inconsistent and he started telling fans that he wanted to leave, so they never really took to Paul Pogba.
“Every week, every month, we see something coming out of Old Trafford about Pogba, his agent, and it upsets the club, the fans, the changing rooms.
“It wouldn’t have happened in our time with Roy Keane, Eric Cantona, Mark Hughes. We would deal with players.”
The former forward went on to suggest that now would be the right time to move the midfielder on.
Ince added: “The best thing for Manchester United is for Paul Pogba to leave.
“I actually thought, when they signed [Donny] van de Beek, that they were preparing for Pogba to leave.
“But they clearly aren’t as Van de Beek didn’t get on today, which is embarrassing for me.
“I don’t envisage him being at the club by the summer. He’s got to go – he wants to go. I think it’s best that both parties part ways.”
