But rather than keep him in the lineup after only a couple of days of rest, Mourinho has explained that he plans to let the 19-year-old properly recuperate before he next picks him.
"I want him to play totally fresh, so he's not playing [against Wolves]".
"I think good results, good performances, they make miracles and bad results and bad performances, they make you look more exhausted, more upset, more ugly, more everything", Mourinho said. Rojo did suit up for the club's under-23 team last week and played 55 minutes. He doesn't need to face more difficulties because of an accumulation of matches.
Nuno will bring his team to have a real go at Old Trafford, where Wolves last won in 1980.
Manchester United manager Jose Mourinho, asked about the influence of his agent, Jorge Mendes, at Wolves: "I think the work in Wolves is good because it's not just about the Portuguese influence - Portuguese manager, staff and players - it is also about getting the right ones and I think they have got good young players and they have also got good, experienced, stable players". Football is a little bit like this.
"I think we are improving as a team".
"A team that yesterday looked very bad, today looks very good and yesterday looked very good, today looks very bad".
However, they'll be up against an ambitious Wolves side who have made a solid return to the Premier League having taken eight points from their five games so far having gained promotion from the Championship last season.
"It's more about the moment and the momentum is very important in the positive and negative way".
'Every player has another level to step up, ' said the manager.
