The Red Devils produced a counter-attacking masterclass to secure a 3-1 win against Arsenal at the Emirates and inflict the Gunners’ first home defeat of the season.
Mourinho’s men had to contend with a barrage of Arsenal chances, with David de Gea in particular shutting out the hosts.
But the Portuguese coach was keen for his squad to share the plaudits rather than to single out the Spanish goalkeeper.
“He was outstanding – all the team was, they gave everything,” Mourinho told talkSPORT.
“They went through different periods of the game where we were very dominant and very aggressive.
“But I saw two very good teams, two very different teams in different moments of the game in a fantastic match.
“Arsenal were brilliant in their attacking football in the last 15 or 20 minutes of the first half and then the team had to adapt again when we went down to 10 men.
“The players were brilliant in that mental approach and [gave] great performances.”
Despite the impressive win, United will be without star man Paul Pogba for next Sunday’s Manchester derby after the midfielder was given a straight red card for a challenge on Hector Bellerin.
Pogba’s absence will be keenly felt given his level of performance following his return from the hamstring tear which ruled him out for 12 games.
And while Mourinho was not in a position to have an opinion on the challenge, he did share his midfielder’s view on Andre Marriner’s decision to send him off.
“I didn’t see it,” Mourinho added.
“But I spoke with Paul and he is very frustrated. He says he had no intention of it [the foul on Bellerin].
“But it was Mr. Marriner’s decision.”
