Match ends, Yeovil Town 0, Manchester United 4.
Yeovil Town 0-4 Manchester United
Alexis Sanchez played a hand in two goals as his Manchester United debut ended in a comfortable 4-0 FA Cup fourth-round victory at League Two strugglers Yeovil Town.
Chile forward Sanchez, who joined United from Arsenal in a swap deal for Armenia's Henrikh Mkhitaryan on Monday, started wide on the left at a packed Huish Park.
The 29-year-old was frequently involved for United and his passes found Marcus Rashford and Ander Herrera for their goals either side of half-time, before he was substituted on 72 minutes.
The Somerset side had started brightly as Jordan Green's early effort was saved by Sergio Romero - who came in as one of 10 United changes - but the lowest-ranked side left in this season's FA Cup rarely looked likely to produce one of the competitions greatest ever shocks.
Jesse Lingard slotted in a third before Romelu Lukaku volleyed a fourth in stoppage time for the visitors, for whom victory came on manager Jose Mourinho's 55th birthday and in his 100th match in charge of the Premier League side.
The Portuguese - who signed a new contract to 2020 with the Old Trafford club on Thursday - has now won 62 of his first 100 games.
Sanchez straight into the side
Former Barcelona forward Sanchez, who scored 80 goals in all competitions for Arsenal in a three-and-a-half-year spell, became the first Chilean to play in a competitive first-team match for United.
Starting out wide, he gave the ball away repeatedly in the first half but was nevertheless lively and showed plenty of confident touches, cutting inside regularly.
He was on the receiving end of a very heavy tackle from Yeovil left-back Nathan Smith, before his curling effort from the resulting free-kick was held by Glovers keeper Artur Krysiak.
His simple pass found Rashford for United's opener, as the young England striker dribbled through the Yeovil box and lost the ball briefly before slotting home after the Glovers failed to clear their lines.
After the break, Sanchez was involved again, sliding a ball to Herrera to slot home the second and mark his 150th appearance for the club in style.
For Yeovil, who knocked out League One Bradford City in the third round, the defeat came with the positive of £144,000 of television broadcast revenue, as they played in the fourth round for only the third time since 1949.
Will United target a record-equalling 13th FA Cup?
United, who have not failed to reach at least the quarter-finals since 2014's surprise third-round loss to Swansea City under manager David Moyes, had won 2-0 at Huish Park in the third round just three years ago.
The FA Cup could prove to be United's best opportunity to win a trophy this season, having been knocked out of the Carabao Cup at Bristol City in December, especially with them trailing Premier League leaders Manchester City by 12 points.
Nevertheless, Mourinho was content to make sweeping changes to his starting side.
The visitors started relatively sluggishly, and stand-in keeper Romero was required to make an important early save to deny Yeovil's Green from close range.
But Mourinho's men controlled most of the remainder of the game and Yeovil - who remain yet to score against United after four meetings - will now return to focusing on their bid to avoid relegation to the National League.
Darren Way's spirited side sit just two points above the relegation zone, 21st in League Two.
For the Checkatrade Trophy quarter-finalists, defeat was their 10th consecutive loss in FA Cup meetings with top-flight sides, having now failed to scored in eight of those.
