Ahead of Thursday's Europa League clash with Fenerbahce, Mourinho spoke of the positive leadership Rooney provides to the United squad.
Former United striker, Robin van Persie, could start against his former club, but manager Dick Advocaat was critical of his performance following the 1-1 draw with Alanyaspor last weekend.
Robin Van Persie is set to return to Old Trafford with Fenerbahce tomorrow night, and he holds a odd place in the heart of Manchester United's fans.
United, who last won the league in 2013, have displayed flashes of brilliance under Mourinho but their erratic performances have threatened to undermine the Portuguese manager's maiden campaign at Old Trafford. Summer signing Zlatan Ibrahimovic is 20/21 to score in this fixture while youngster Marcus Rashford is 13/10 to grab a goal. "I am looking forward to it", van Persie said in an interview with MUTV.

The U.N. and rights groups estimate the conflict has killed at least 9,000 people and displaced almost 3 million more. A USA official said that additional radars could have been used in the Saturday attack.
Morgan Schneiderlin and Anthony Martial could return from injury for Manchester United against Fenerbahce in the Europa League. "I'll make sure I'm ready and have no excuse when I'm needed".
Rooney forward further said he just needs to keep working and trying to get into the team.
"Liverpool was the toughest game before the Europa League and then we've got Chelsea and City". "I cannot confirm if he will play tomorrow but he is fit and it is time for him to go back to the levels we know he can achieve".
"If we play with a team that is not good and strong, we won't have a chance".
