Manchester United boss Jose Mourinho concedes Paul Pogba is a doubt for their Champions League clash with Sevilla.
Pogba, 24, missed the win over Liverpool on Saturday with a thigh injury sustained in training on Friday.
"I don't know," the United boss said when asked about Pogba's availability for Tuesday.
"He's downstairs now and I will go and speak with him. The injury? It was contact with a player in the last minute of the training session (on Friday).
"If I finished the session one minutes before it wouldn't have happened."
