The veteran midfielder set up the only goal of the game, netted by Javier âChicharitoâ Hernandez, but was disappointed the Reds couldnât build on it in the next 80 minutes.
âSometimes it can happen that way,â said Giggs. âWe scored an early goal and then we sat back. We shouldnât have done that really.â
The Welshman acknowledged this trip to his homeland was a difficult fixture, with Swansea defying their newly-promoted status to pick up 13 points and concede only one goal at home â an own goal â prior to Unitedâs visit.
âItâs a tough place to come. Their record this season shows that, they were unbeaten here until today. So we knew it would be tough.â
Giggs accepted international breaks can impact negatively on clubs when their players return, but wouldnât cite this as a reason why Unitedâs 1-0 win was worryingly slender.
âYou have different players at different fitness levels,â he said.
âSome of our players hadnât had a game for two or three weeks and some, like Phil Jones and Nani, had two tough games.
âBut thatâs not an excuse. We probably need to play better if weâre going to get more positive results.â
