That is according to defender Chris Smalling who was among the goalscorers in the 4-1 demolition job of the reigning champions at Old Trafford.
A first-half rout from Smalling, Juan Mata, Marcus Rashford and Paul Pogba arrested a run of three-straight losses and the centre-half feels similar performances in the future will have any standard of opponents running scared.
"I think there was a lot of talk for us to sort of turn the situation around because that was obviously a very bad week, the three results," said Smalling.
"But we could only really sort of show that we've changed by doing it on the pitch and I thought that first half was a great performance and really gave us a marker now to make sure we sort of attain to that.
"I think if we can start the game with that tempo, I think there's not many teams that can live with us.
"It is about finding that consistency to make sure that we stay at that top end of that table because we don't want any more blips. We've had our blip hopefully for quite a while."
"Hopefully we can take this into next week because we've got another two big games and at home as well so hopefully we can put on a show."
United's next match takes place against Ukrainian side Zorya Luhansk on Thursday night.
