Manchester United vs. Wigan Athletic: Score and Reaction from 2017 FA Cup

Manchester United cruised into the fifth round of the FA Cup on Sunday, beating Wigan Athletic 4-0 at Old Trafford. 

Marouane Fellaini opened the scoring late in the first half, and Chris Smalling doubled the lead with a powerful header after the break.

The second goal opened the floodgates, with Henrikh Mkhitaryan and Bastian Schweinsteiger adding their names to the scoresheet before the fourth-round tie came to a close. 

As expected, United manager Jose Mourinho made a host of changes to his starting XI, introducing the likes of Anthony Martial, Sergio Romero and Schweinsteiger, per the club's official Twitter account:

The match didn't get off to the best of starts, as both teams prioritised the midfield battle. Flying tackles and strong duels were the norm, and chances were rare.

The visitors didn't help matters by sitting back and inviting pressure once United got hold of the ball, with spaces out wide being limited. The first chance fell to the Latics, as Dan Burn headed the ball to Callum Connolly, who drew a save from Romero.

Wigan mainly threatened through set pieces, while United tried to patiently build their attacks with little success. Wayne Rooney and Fellaini couldn't get a real grip on the midfield proceedings, while Martial found himself isolated most of the time.

Juan Mata powered a shot over the bar after some good work from Luke Shaw, and Max Power tried his luck from distance, putting Romero to work.

Mkhitaryan squandered a golden opportunity to give his team the lead after 32 minutes, missing an open net from just yards away. As BBC Sport noted, it was a microcosm of the Red Devils' attacking woes:

The United pressure mounted as the half was drawing to a close, however, and the visitors started to struggle. Mata had a few decent looks on goal, while on the other side of the pitch, Michael Jacobs whiffed a shot from a promising position.

It was Fellaini who broke the deadlock just before half-time, powering home a trademark header after a fine delivery from Schweinsteiger. Sports writer Liam Canning believes the Belgium international doesn't get the credit he deserves:

The pace once again dropped at the start of the second half, but only briefly. Rooney provided Timothy Fosu-Mensah with the first opportunity after the break, but the 19-year-old full-back couldn't keep his composure.

Schweinsteiger powered his way through the box before he had a shot blocked, and Romero made a superb save to maintain the lead after giving away the initial chance.

The hosts needed a second goal, and it came through Smalling, who got on the end of a great cross from Martial. Per WhoScored.com, the 21-year-old forward has been in solid form of late:

The second goal effectively killed Wigan's resistance and made it much easier for the Red Devils to move the ball around. Fosu-Mensah and Fellaini both made their way off the pitch—the former with what looked to be a knock after landing awkwardly.

Connolly drew another save from Romero, but less than one minute later, Mkhitaryan made it 3-0, finishing off a perfect counter-attack.

Bleacher Report UK couldn't help themselves:

And there were more goals to come, with Schweinsteiger adding his name to the scoresheet. The German pounced on a weak header from Ander Herrera, capping off the chance with a lovely finish on the turn.

Martial thought he had made it 5-0 shortly before the final whistle, but the goal was called back for a foul from Schweinsteiger. It was unfortunate for the former Bayern Munich man, who had a fantastic outing.

He took to Twitter to thank the fans for coming out:

As shared by Stuart Mathieson of the Manchester Evening News, Mourinho said Schweinsteiger will receive more chances, and he also gave an update on the club's plans for the rest of the January transfer window:

Debutant Axel Tuanzebe also spoke after the match, via the club's official Twitter account:

United's next match will be in the Premier League against Hull City on Wednesday. Wigan are back in Championship action on Friday, hosting Sheffield Wednesday.
