The French midfielder is currently sidelined with the muscular problem but Manchester United have been coping with his absence as they coasted to a 4-0 victory over Crystal Palace on Saturday.
It remains to be seen how long exactly Pogba will be out for as the French midfielder looks to get himself back fit as quickly as possible.
However, Mourinho has insisted that Manchester United cannot dwell on their injury problems and instead urged his side to focus on the things that they can control.
Speaking at his post-match news conference after the win over Palace on Saturday, Mourinho said: “We never miss the players that are injured.
“That is our way of thinking. They are injured, we don’t think about them.
“It is an opportunity and a moment for others to step up and get the chance, so I think that is good.
“When we moan all the time about injuries it looks like we don’t trust the other people and we have to.”
Manchester United return to Premier League action after the international break with a crunch clash against bitter local rivals Liverpool at Anfield.
Mourinho’s men have made a fine start to the new season and currently find themselves in second place in the table and level on points with Pep Guardiola’s leaders after seven games.
The Portuguese coach is aiming to guide Manchester United to their first Premier League title since their final triumph under Sir Alex Ferguson back in 2013.
