Manchester United v Swansea City - As it happened

United let a marvellous chance to go up to third go to waste. Swansea were better in the first half but Rooney put his side in front from the spot. The hosts failed to put the fixture to bed and Sigurdsson made them pay with a wonder strike into the top corner.
