Manchester United returned to winning ways in the Barclays Premier League after earning a hard-fought victory against Swansea to end an eight-game winless run.
Anthony Martial after a muted display by his standards in the first half, changed the game by heading United’s first and then set up Rooney for the second.
History seemed dangerously close to being repeated for the home fans when Sigurdsson – the matchwinner in Van Gaal’s United debut – steered home Modou Barrow’s cross with 20 minutes to go.
Swansea had won all three of their league meetings with Louis van Gaal’s Manchester United – including the Dutchman’s very first match in charge.
Rooney’s afternoon up to that point had been full of industry but short on inspiration. However United’s captain improvised brilliantly to flick Martial’s cross round his standing leg and into the far corner past a rooted Fabianski for the winner.
Manchester United move up to fifth, two points behind Tottenham.
