Swansea City won their first ever game at Old Trafford to knock 10-man Manchester United out of the FA Cup this afternoon.

The two sides went in level at half time because of goals from Wayne Routledge and Javier Hernandez, before Wilfried Bony won the third-round tie with a header in the 90th minute.

United substitute Fabio da Silva was shown a straight red card for a rash challenge just minutes after coming on, but United looked like they would hold on for a replay until Bony grabbed the headlines.

Here, Sports Mole casts its eye over another disappointing result at home for United this season.

Match statistics:

United:
Shots 7

Swansea:

Possession 51%

Fouls 12

Was the result fair?

Perhaps. A draw would have probably been the fairest result, but considering that United were favourites and at home, you have to give credit to Swansea for the way they played.

United's performance

Yet another glum day for supporters of the Red Devils as they watched their side go down again at home this season. Star strikers Robin van Persie and Wayne Rooney were missing but even so, it was a poor showing from those who did start. They may now be out of the FA Cup and feel that the league is out of their grasp, but United are still in contention in the Capital One Cup and the Champions League. It already feels like manager David Moyes has to win one of those for his debut season at Old Trafford not to be a total disaster.

Swansea's performance

A great display from the Swans as they managed without captain Ashley Williams and Spanish forward Michu. Bony took his goal very well, while in defence the likes of Danny Welbeck, Javier Hernandez and Shinji Kagawa were kept fairly quiet. Having more possession than United at Old Trafford just shows how well Swansea passed the ball.

Sports Mole's man of the match

Wayne Routledge: The Swansea winger finished cleverly by lobbing Anders Lindegaard and then set up the winner. He still had plenty left in the tank and used his pace to get to the byline before crossing for Bony to head home.

Biggest gaffe

Fabio made such a stupid decision to go in high on Jose Canas and it ended up costing United as a missing right-back helped Routledge set up the late winner.

Referee performance

Mike Dean made the right call in sending off Fabio for his high, studs-up tackle. His solid game was somewhat marred by the below reaction to Swansea failing to make the most of the advantage he gave them. Brilliant.

What next?

United: Next up for United is a trip to Sunderland in the first leg of their League Cup semi-final on Wednesday. Then Swansea visit again in the league on Saturday.

Swansea: The Swans will be hoping for a repeat performance to end their six-game winless streak in the league when they return to Old Trafford.
