Mason Greenwood sparked a huge reaction with his performance in the FA Youth Cup on Monday night.
To put the game into perspective, Chelsea haven't lost a single FA Youth Cup game since the 2012-13 season, having romped their way to the last five trophies.
So, in the third round fixtures on Monday, it was a remarkable result for United to end Chelsea's incredible run of success and in emphatic fashion, too.
Greenwood was such a major part of that victory as well, scoring a hat-trick on the night as the Red Devils ran away 4-3 winners.

Manchester Evening News writer Samuel Luckhurst wrote in his report: "Jose Mourinho was missing and missed out on another Mason Greenwood masterclass.
"You would have to be joyless not to enjoy Greenwood's development, though. While 2018 has become an annus horribilis for United it is Greenwood's mirabilis.
"Pre-season squad inclusion, a professional contract, a first-team squad promotion and now a Youth Cup hat-trick. It has got better and better."
Mason Greenwood's individual highlights
It's been quite some year and such a remarkable performance against Chelsea has thrust his name right into the mainstream.
United fans were going wild for his hat-trick across Twitter, with the slogan 'remember the name' quickly doing the rounds.
Unsurprisingly then, one supporter has already rustled up Greenwood's highlights from the game and it makes for incredible watching. Take a look at the video down below:
Believe the hype, this kid is special.
Fresh from making the bench for the recent Valencia trip, Greenwood opened the score after just seven minutes, punishing Chelsea goalkeeper Karlo Ziger for a botched Cruyff turn.
He even attempted an audacious goal from the halfway line, trying to replicate David Beckham and Wayne Rooney's achievements in the first-team.
His hat-trick was eventually completed in trademark fashion with a shrewd finish across the goalkeeper as United saw out the win.
It incredibly elevated Greenwood's tally to 21 goals across 19 appearances this season.
Making the first-team as a young and exciting United forward is no easy task, with players like James Wilson proving a foreboding example.
You have to look back to players like Mark Hughes to see a player who truly cemented his place in the United first-team from the academy ranks.
Nevertheless, it seems Greenwood is more than capable and in the words of Luckhurst: "Mourinho missed out on history."
