Score: Yeovil Town 0 - 4 Manchester United
Goalscorers: Marcus Rashford 41', Ander Herrera 61', Jesse Lingard 89', Romelu Lukaku 90' + 3'
Yeovil Town held their own and then some in the first half before being swamped over by Manchester United's sheer class on the ball and strength in depth. By the end, United were simply too good for the League Two outfit.
Here, then, are the key talking points from an entertaining FA Cup affair.
#5 Jose Mourinho and Ander Herrera celebrate milestones in style
This was Jose Mourinho's 100th game in charge of Manchester United - on his 55th birthday, incidentally - while it was also Ander Herrera's 150th game for the club. United won this game the Mourinho way, absorbing a lot of pressure early on - a product as much of Yeovil's intensity as deficiencies from United's end (Matteo Darmian, hello) - before finishing with a flourish as the manager's changes swamped the home side completely.
Herrera, meanwhile, bossed the midfield alongside Michael Carrick and Scott McTominay and was his all-action self for the duration; his goal - his second one at Huish Park, after the screamer he scored last time around in Louis van Gaal's last season - a richly deserved reward for his performance.
#4 Jake Gray has a right to be annoyed with the goings-on at the end of his crosses
Whenever Yeovil Town won a freekick in an area of the pitch from which crosses were more plausible than shots-at-goal. United's defence looked like nervous wrecks, and that's thanks to Jake Gray's impeccable delivery.
Whether from the right flank or the left, whether out-swinging or in, Gray's deliveries caused all sorts of problems for Marcos Rojo, Victor Lindelof and co. in the United area and he'd be right to be annoyed with the likes of Omar Sowmunmi, Sam Surridge, and Francois Zoko - all of who wasted presentable opportunities to put Yeovil on the scoresheet.
In fact, Yeovil's best chance came when one of Gray's balls was headed into Romero's arms by Sowunmi from about six yards out. With the score at 0-0.
The 22-year old has bounced around the lower leagues for a while now since being released from Cyrstal Palace's academy but if he keeps up this level of performance - and set-piece delivery - he should make it up the ranks soon enough.
Oh, and a word of appreciation for Ryan Dickinson, who dominated Matteo Darmian and Juan Mata all night long down his left flank and swung in a couple of sumptuous crosses romping forward from left back!
#3 Scott McTominay comes of age
Not even the most ardent followers of Manchester United's Youth and Reserve Teams would have picked Scott McTominay to be the lad who gets boosted up into the senior team; but the young Scot has come leaps and bounds from a steady-but-not-spectacular midfielder to an all-action, commanding presence in the middle of the field.
In a midfield that contained Michael Carrick and Ander Herrera, and against tough-tackling no-nonsense opponents, McTominay more than held his own, directing play down the middle, running into channels, passing the ball around neatly, taking it on the half-turn with poise and even - at one point - telling Carrick where to be during a certain phase of play.
Playing under the aegis of Jose Mourinho has most definitely helped him - like it did Jesse Lingard, Anthony Martial, and Luke Shaw - and he continues the long tradition of United academy products being eased into the senior team - Angel Gomes, just 17, was immensely impressive in the five minutes he got too.
For the average United fan, it's heartening to see Mourinho buy into, at least partially, the 'United Way'
#2 Darren Way's side can be proud of themselves
Darren Way's personal story - of captaining Yeovil into League Two from the backwaters of non-league football in 2003, not almost losing his life in a car accident in 2003 and having to learn how to walk again, to getting into the Yeovil coaching system in 2010 and becoming first team manager soon after - is one that deserves to be told the world over, and thanks to the visit of Manchester United - and their newest signing - that tale definitely reached more ears, and eyes, than ever before.
If that had been the only thing he, and Yeovil Town, could take away from this night, it'd have been a decent one - but it wasn't. For the overwhelming story was just how well a side 87 places below Manchester United - about as far apart as two sides can be in England's four structured tiers of football - played for the vast majority of the match.
Pressing high up the pitch, and moving it about with a slickness that was disconcerting initially, they suffocated their more illustrious visitors and were it not for a lapse in concentration from young Tom James - and some shoddy finishing at the other end - would have had their most perfect first half in ages.
As the second half wore on, and what was essentially an u-23 side (bar a couple) tired and wilted under the pressure, it was understandable that a hungry United side were able to pick them apart.
Even though the score might read 4-0, the applause Huish Park reserved for their heroes at the end of the 90 spoke to just how valiant their performance was.
#1 Alexis Sanchez is the ideal Jose Mourinho player
Ander Herrera summed it up well - “I think he [Alexis] can play anywhere, he fights for every ball, he runs for everything. We are going to enjoy him.".
United are going to enjoy him, and Jose Mourinho is going to enjoy him. While many superstars may have thrown a strop at having to make a debut on the lumpy, wobbly, Huish Park pitch - Alexis just rolled his socks and relished the challenge.
He was at the heart of everything United did on the night - wherever he went, the ball followed him, and his first 70 minutes in a United shirt provided a promising glimpse of what could lie ahead.
He did, of course, misplace passes often - but unlike at Arsenal, where possession is God - it is exactly this fearless risk-taking that Mourinho, and United, need to push them past the final dredges of Louis van Gaal's mind-numbing sideways passing philosophy.
On closer inspection, Alexis appears to be Mourinho's inner-footballer-incarnate on the pitch, the kind of fighter he wants in every team of his; and this just might be the beginning of something good.
