The 24-year old will fly back to France after his father passed away on Friday from a long-term illness. Pogba was not in the squad for United's defeat at White Hart Lane on Sunday.
Speaking to the club's website before the match, Mourinho said on Pogba: "I don't think (he will be available).
"I think that his dad's funeral has to be between Tuesday and Wednesday in France.
"I don't think that Paul has the conditions to play. We have left him completely free to be back when he thinks he's ready."
