Manchester United's teenage sensation Marcus Rashford continued his excellent start to the season in Saturday's 4-0 win over Crystal Palace.
The academy graduate repaid his manager's faith with an immediate assist for Juan Mata before notching another assist for Marouane Fellaini with a superb free kick in the second half.
Crystal Palace have lost each of their opening seven games of the season and have incredibly failed to score a single goal.
They never stood a chance against an in-form Manchester United team who are unbeaten at Old Trafford since last September.
Summer signing Romelu Lukaku added a goal late on to continue his incredible start to the season - the former Chelsea and Everton striker has netted in each of the opening seven Premier League games.
Fellaini scored a brace in Paul Pogba's absence and Mourinho heaped praise on the afro-haired Belgian midfielder.
"He [Fellaini] is a great player and character and we have a good relationship," said Mourinho. "A strong character who resists the difficulties here. Some people did not recognise his qualities so he has to be a strong character.
"He is a fighter. I am really pleased that I help him reach this level and to change the perception that the fans have now. I am really happy for him.
"Fellaini has important qualities and I try and use his qualities depending on the situations. He plays with me as a defensive midfielder and as a second striker and adapts to the needs of the team."
Rashford's beautiful piece of skill
Not picked up on Match of the Day, most Manchester United fans - who were unable to get a ticket for the game - missed Rashford's glorious piece of skill in the first half.
The 19-year-old England international controlled the ball brilliantly before executing a lovely shoulder pass to his teammate.
The youngster has been competing with Anthony Martial for a place in Mourinho's starting XI but, despite the Frenchman's impressive form, Rashford has been preferred in six of the seven Premier League games.
