Full-time: Shrewsbury 0-3 Manchester United
A youthful-looking United side now appear happy to play keep-ball. The Red Devils have dominated this game from start to finish, and you can hardly blame them.
In fact, they almost grab a fourth through Lingard, but his effort is well saved.
And with minutes remaining in the game, the hosts squander their best chance of the game. Ogogo with the effort that sails wide of the post.
There was a chance to have his name up in lights.
This has all been too easy for United. Micky Mellon's men haven't done enough to upset their famous opponents.
The game is sure to have helped the club's coffers, but Shrewsbury will be frustrated by their performance.
United's dominance this evening is evidenced by the possession stats.
The hosts have not made 100 successful passes tonight; United, on the other hand, have made almost 500 successful passes.
Mind you, given the relative costs of the two sides, that shouldn't come as a real surprise.
Yep, it's all over for Keane. He's lying on the ground and he can't continue.
What a sad sight for the youngster. He's got his chance with the United first-team and injury has spoilt it for him.
The Red Devils are down to ten men.
Another close call for United, and the ball falls to Will Keane.
His effort bounces back off the post. And sadly for the youngster, he appears to have pulled his groin.
United may have to finish the game with ten men.
United open up the Shrewsbury defence again.
Lingard is one-on-one with the goalkeeper but pulls his shot wide. He should have scored.
The England international also appears to be limping - which isn't ideal, as United have made all of their subs already.
United's third and final change, now. It's a logical one, too: Anthony Martial is coming off to be replaced by Will Keane.
He recently scored five in an under-21 game against Norwich City. He will hope to get on the scoresheet in the next few minutes.
Van Gaal probably took Mata off with United's upcoming games in mind. He cannot afford any more injuries.
That being the case, why not replace Martial?
Another change for United. Juan Mata is making way for Pereira, who will be keen to impress during a rare outing with the first team.
The Brazilian has about 25 minutes to show what he's made of.
Well, there we have our answer.
United have put this cup tie beyond doubt with another eye-catching goal. Herrera floats the ball in from the left side and Lingard meets it with a first-time volley.
A quality goal, that, to cap a good evening for United.
GOAL: Shrewsbury 0-3 Manchester United (Lingard)
Right, there's 30 minutes left in this cup tie. Have Shrewsbury got what it takes to get back in the match? Can they create some goal-scoring opportunities?
Or will United ease to a much-needed win? Thus far, it's been a surprisingly comfortable evening for Louis van Gaal.
Martial misses a sitter from four yards!
The ball is played in from the corner, Mata flicks it on and Martial misses from close range.
That would have sealed the victory, but the Frenchman squanders the opportunity.
There's a bit of lingering controversy surrounding United's second goal.
Mata's shot went directly into the net, but there were three United players who were stood in offside positions at the time.
The trio were stood in the goalkeeper's line of vision. On reflection, the ref may think he should have blown for offside.
Just in case you'd forgotten, Larnell Cole is a former Manchester United player.
He made one appearance for the first-team, appearing as a substitute against Leeds United in the League Cup in 2011.
Famously, that match ended with Dimitar Berbatov playing as a centre-back.
A couple of changes at half-time. Larnell Cole has been introduced by the hosts, and they've switched to a 4-4-2.
United have made a change, too. Joe Riley comes on for his first-team debut, Borthwick-Jackson has been replaced.
United lead 2-0 and it's no less than they have deserved in all honesty. The Red Devils have been unusually bright and breezy on the ball, and have always carried a threat through the likes of Martial.
The hosts have failed to perform, on the other hand. There's been a lack of spirit in their play. They really needed to launch themselves at their opponents, but in truth, it's all been a bit underwhelming from them.
The resultant freekick is up, over the wall and into the net.
Beautiful strike from Mata, who made that look incredibly easy. That's 2-0 to United and it's a long way back for the hosts now.
GOAL: Shrewsbury 0-2 Manchester United
Beautiful one-two between Martial and Mata on the edge of the box.
The Frenchman is fouled on the edge of the box, but it's just a yellow for Whitbread.
That was eye-catching stuff from United, though, who have been persistently accused of being dull this season.
United's dominance is underlined by the shot stats.
The away side have already had 13 shots on goal, as compared to zero for the hosts, who must adjust their pre-game plan now.
They've started to fly into the odd tackle since the goal has gone in, which may not be the worst option.
