The France international will be sidelined for six weeks with a damaged hamstring.
Pogo, 24, pulled up in Tuesday night’s Champions League win over Basel at Old Trafford.
The midfielder left the ground on crutches and underwent scans.
Starsport also revealed yesterday that the £89m star also suffered damage to his thigh.
And according to The Sun, Mourinho is furious with Pogba, with the United boss blaming the former Juventus ace for ignoring medical advice.
They say Pogba was given clear instructions on how to deal with his long-standing hamstring injury.
However, the United star instead received treatment from a personal trainer.
The Sun say Pogba has ignored the club’s advice and has a private training regime.
And Mourinho reckons that made his star man more prone to injury.
In good news for United, Zlatan Ibrahimovic is edging closer to an Old Trafford return.
And Pogba has hailed the 35-year-old, claiming he’s instrumental for the Red Devils.
He said: “He [Ibrahimovic] is very important to the group and when he is in the team he makes the other sides scared of him as well.
“When they see Zlatan and know we have big players like this, they fear the club.”
