Louis van Gaal left frustrated as Swansea do the double over Manchester United
Welsh side win 2-1 to leave Dutch coach bemused

Manchester United manager Louis van Gaal expressed frustration after his side squandered a chance to avenge their Premier League opening day loss to Swansea City in a 2-1 defeat.

The game was won 17 minutes from time when Bafetimbi Gomis inadvertently deflected Jonjo Shelvey’s long-range strike over David de Gea to bring United’s 19-game unbeaten run to a halt.
