The second half has all been about Manchester United, with Wayne Rooney scoring a close range bicycle kick to bring the sides level, but now Swansea's new signing Gylfi Sigurdsson has shown exactly why he is worth £10m to the Swans by scoring to put his side back in front. As Van Gaal stared on with a blank expression, the Icelandic attacking midfielder - who was under-used at Spurs unfairly - slotted the ball home with the side of his foot after some good work by both Montero and Wayne Routledge. It was very much a case of bad defending - and further proof that the side's defensive options need to be seriously strengthened if United are going to compete for a top four berth. Chris Smalling completely switched off before the free-kick, and then Ashley Young - in at left-back after the change of system from 3-5-2 - was caught under the crosses Sigurdsson slotted his finish in. https://twitter.com/TheFootyVines/status/500632307611734016 Sigurdsson has scored eight goals in 19 Premier League appearances for Swansea, reinforcing his key role in the ream, and 7 of his last goals have been scored away from home. To say he is valuable is beyond under-estimation. Can United equalise again?
