The Red Devils looked on course to preserving their unbeaten start to the new season as Juan Mata broke the deadlock early in the second half as he got on the end of a Luke Shaw cross to net his first of the season.
However, just like in the corresponding fixture last season, the Swans roared back and claimed all three points thanks to quick-fire goals from Andre Ayew and Bafetimbi Gomis at the Liberty Stadium
Victory in Wales means the hosts have beaten United for the third successive clash and they denied their opponents the chance to go into the international break in second place in the Barclays Premier League table.
van Gaal spoke to Sky Sports after the game and hit out at his team’s failure to cope with the Swans’ change of formation for a brief spell in the second half:
“The opponent changed their shape and we could not cope, that is not good,” the Dutchman said.
“We lost in that five minutes and it is a pity because we controlled the game.”
“You have to be compact, we were probably too dominant to have the sense to do that.”
“We could have scored much more goals, that is not the problem. You need a little bit of luck,” van Gaal added.
