It was De Gea, however, who Mourinho singled out for special praise, telling BT Sport, "I told him after the match, what I saw today was the best from a goalkeeper in the world". The United resistance prompted the Frenchman to state De Gea was "man of the match by a clear mile".
The team defended well for 90 minutes.
De Gea produced a staggering 14 saves to equal a Premier League record before Lacazette temporarily halved the deficit before Lingard's third goal in the English capital.
Jesse Lingard (twice) and Antonio Valencia netted for the Red Devils, in what was an entertaining clash. "All the effort from the players was magnificent".
There was no hiding Mourinho's joy, however, at an impressive all-round United display. "I didn't see the tackle", Mourinho said.
"It was phenomenal game". The Portuguese is renowned for encouraging the home side to have more of the ball when his teams play away games and hitting the opposition on the counter attack is exactly what he wanted.
"Of course, they can say they had chances, but we fought and had a great goalkeeper, too".
"This was a game that was incredible, phenomenal, fantastic and a deserved three points".
"I think we didn't start well at all at the back and we are guilty of that", Wenger told the BBC.
"Look, I'm angry and disappointed because when you produce that quality and have nothing to show for it it's hard to accept", the Frenchman said during his post-match interaction with the media. "But you can not make the mistakes we made at the beginning". "I just know that Paul is frustrated and a bit disappointed with his (France) colleague (Laurent Koscielny) for his reaction because everyone knows Paul is a clean player and it was not his intention".
