Marcus Rashford and Anthony Martial starred as United eased past the Sky Bet Championship club in the Carabao Cup third-round tie, and Mourinho hailed a professional performance.
When asked how impressed he was with 19-year-old England international Rashford, Mourinho told Sky Sports:
“Yes, but Martial was good, (Juan) Mata was good, (Jesse) Lingard was good.
“I think everybody in attacking areas gave a good dynamic to the team and especially happiness. We look happy playing football in this moment and that’s what I want.
“They all want to play, they are all ready to play, they all want to use the minutes they have on the pitch to try and improve and have the pleasure of playing.
“I enjoy very much that commitment, that pleasure in the game, (there were) some great performances and the team collectively enjoyed the game.”
Mourinho felt the result suited everybody, and added:
“It was a professional performance, we played seriously.
“I think the first half we gave no chances to the opponents, we went strong, gave a very good dynamic and arrived 3-0 at half-time.
