Goals from Ki Sung Yueng and Gylfi Sigurdsson either side of a spectacular Wayne Rooney overhead kick ensured the Swans left Manchester with a well deserved 2-1 victory and break the record for the first time in 42 years.
“It is very disappointing that we have lost our first home match,” Van Gaal told BT Sport in his post game interview.
“We didn’t reach the level we can play at. That is disappointing because we have done it much better and when you cannot do it in your first home match that is disappointing, especially for the fans.”
Manchester Coach, Van Gaal accepts the responsibility of the failure of the team and attribute their failure to not been playing as a team and some wrong decisions that was made before the match.
“We were very nervous in first half, made the wrong choices and that is a pity. In the second half we never played as a team, therefore I’m responsible,” Van Gaal added.
“We had more chances than Swansea but that shall say nothing about the result. It is the goals that count. I thought we would win (when the scores were tied at 1-1 in the second half) but because we are not playing as a team in the second half we made the wrong decisions going forward” he concluded.
