A late header from Wilfried Bony gave Swansea City their first ever win at Old Trafford, knocking Manchester United out of the FA Cup in the process.
Wayne Routledge put the visitors ahead in the 12th minute, before Javier Hernandez equalised just four minutes later.
Bony's winner in the 90th minute means Swansea will play either Birmingham, Bristol Rovers of Crawley in the fourth round.
