Mourinho, 55, confirmed the French midfielder’s absence was because of an injury, but the United boss could not be specific as to the extent of the injury, or for how long Pogba would be missing from the first team.
“He is injured,” Mourinho told Sky Sports.
“Yesterday in training, an unlucky situation, he is out.
When asked how long Pogba would be out for, Mourinho replied: “I don’t know.”
Reports surfaced last week that Pogba had sustained a gash to his thigh during a training session at Carrington.
This is the second time the Frenchman has been ruled out by injury this season, after he missed seven games at the beginning of United’s campaign due to another thigh injury.
Pogba has come in for criticism of late due to his lacklustre performances in the league. Former Man Utd right-back and captain Gary Neville claimed, during Sky Sports’ half-time analysis of the Crystal Palace win, that he approached the match, “like a YouTube or an Instagram video.”
The injury news also comes after reports that a rift has opened up between Mourinho and his £89m signing, which has contributed to speculation over the France international’s future at Old Trafford – this has been denied by Mourinho.
United coped well in Pogba’s absence, beating Liverpool 2-1 at Old Trafford thanks to two goals from Marcus Rashford, as the Red Devils move five points above their rivals in the battle for second place.
