His side sit comfortably mid-table with nine points from six games in their first season back among the elite but he declined to indulge the away fans' chants of "Nuno's the special one".
A draw at home to Wolves was not the result Manchester United wanted.
Manchester United suffered consecutive losses to Brighton and Tottenham Hotspur to lose ground in the title race after three games.
Mourinho said the 19-year-old Diogo Dalot, who impressed on debut in Wednesday's 3-0 win at Young Boys, would be rested for Saturday's meeting with Wolves at Old Trafford.
'They are getting the points and performances that makes everybody feel - I include myself - that they are going to have a very stable season, very far from the problems that normally a team from the Championship has'.
"What is most important for me is that we are growing".
"But I think the work being done at Wolves is good because is not just about Portuguese influence, a Portuguese manager, staff and players".
Only his redoubtable goalkeeper De Gea, without whom United would surely have been staring at a first defeat in the fixture since 1980, will feel able to rise entirely above the criticism.
Wolves had looked nothing like a promoted team, playing composed and intelligent football and they earned their reward with a finely worked goal after the break.
United, though, have conceded only once during the winning sequence.
Jesse Lingard had a good effort tipped over by Rui Patricio in the 67th minute and Marouane Fellaini had a header from a Luke Shaw cross well dealt with by the Portuguese keeper.
"I think the team is more compact, more solid".
"We are growing game by game".
