Manchester United manager has said that his team were unlucky to lose to Swansea City in their Premier League clash.
United went down 2-1 at the Liberty Stadium, Bafetimbi Gomis deflecting the winner beyond David de Gea.
Van Gaal told the post-match press conference: "Of course you can say we dominated the game but the only thing we could have done more was score more out of the chances we created. Today we were the unlucky team. I think we created enough chances. We were the dominant side in both halves.
"Conceding so quickly after opening the scoring was important. It was a throw in for Swansea and we should have been more organised. But it was a good goal by Swansea.
"Today we played well - only we forgot to score. We have to be more effective."
United have dropped to fourth in the Premier League, behind Arsenal.
