Manchester United face Fulham this weekend as they look to end a four-game winless run in the Premier League.
And he hopes to have some players back from injury after a defensive crisis which has seen him have to move his players around over the last few weeks.
But he has revealed he won’t speak about two long-term casualties: Victor Lindelof and Alexis Sanchez.
When asked if any of the injured players are back for this weekend, he said: “I don’t know.
“Training session, 11 o’clock will give us some answers, Smalling, Jones, Martial, Bailly.
“Of course Lindelof and Alexis, we don’t even speak about them but we need answers and for sure we are going to play with players not in the maximum of their potential but players who will put themselves available for the team like Smalling did in the last match, like Jones did against Southampton, players in difficulty who go one step forward to try and help the team.”
Sanchez has flown back to Chile as he faces six weeks on the sidelines.
He has been given time off to recover in his homeland as he tried to shake the malaise that has engulfed his time at United.
United are 18 points behind league leaders Manchester City and eight behind the Champions League places.
And Mourinho has told his players to step up to the challenge.
“I want to be positive and think we are going to win,” he said.
“But if we don’t, we give credit to the people that deserve credit.
“The game is not going to be 11 against 0, it’s going to be 11 against 11, good players in the other side, I repeat that the position, the points sometimes don’t say much about the real potential of the team.
“One of the two most important managers in the history of the Premier League, in my opinion, so they have the potential to come here tomorrow and to give us a very difficult match.”
