Manchester United produced arguably their finest performance under manager Erik ten Hag as Tottenham were swept aside in the Premier League at Old Trafford.
The scoreline does not do justice to United's vast superiority as only the brilliance of Spurs keeper Hugo Lloris denied them the truly emphatic victory they deserved.
Lloris made five outstanding saves in the first half alone as United rained in 19 shots on the Spurs goal, which somehow remained intact.
Fred finally broke the deadlock two minutes after the break, his shot carrying a degree of good fortune as Lloris was finally beaten by Ben Davies' deflection, but it was no more than United deserved for a display high on quality and intensity.
United moved out of sight after 69 minutes when Bruno Fernandes curled a precise right-foot finish beyond the stretching Lloris in front of an ecstatic Stretford End.
Spurs boss Antonio Conte later said: "I think in the game, United deserved to win. They played a really good game. In our side, I think the level has to be higher, we need to improve a lot and to try and be better than today.
"The first goal was a deflection but at the end I have to be honest and tell you United played better than us. They created more chances than us. In to the pitch we put will but we have to show this level we need to try to improve and be better. The level was high and United showed today they are much better than us today.
"I consider United a really good team and you know very well what they did in the transfer market and what they can spend. You are talking about two different levels. In this type of game we can do better. We struggle against Chelsea and Arsenal and today.
"We have to try to improve and there is only the work to do this. I repeat, especially in this type of game when the atmosphere is a lot of noise, United are an important team, we can improve and increase our level."
