Swansea manager Brendan Rodgers refused to blame Angel Rangel after the defender's error helped Manchester United to a 1-0 win at the Liberty Stadium.
The Spaniard's careless pass out of defence was seized upon by Ryan Giggs, who duly set up Javier Hernandez for the Mexico international to slide home the winner in just the 11th minute.
The result ended Swansea's unbeaten home record this season, but Rodgers said: "The blame is on me, I ask the players to play that way."
Rodgers continued: "He could have had his touch and smashed the ball up the pitch, he was just slightly off balance trying to play around the corner.
"We look to pass our way out of trouble. The main thing to learn from it was that Ryan Giggs, who was brilliant even though he is almost as old as me, took a great touch into the box and they scored. That is the reality of playing the top sides, but we are learning all the time.
"Angel has been fantastic so there is no blame on him at all."
While the visitors were comfortable for long spells of the game, with Wayne Rooney and Michael Carrick turning in outstanding individual displays, the hosts were guilty of spurning a gilt-edged chance to level 11 minutes after Hernandez had given United the lead.
The opportunity fell to Scott Sinclair after a deflected Wayne Routledge shot found its way into his path to leave him with an open goal seven yards out, but the former Chelsea man miscued and the ball rebounded away to safety off his standing foot. And Rodgers admitted that it had been a "straightforward" chance.
"That was the difference, they took their chance, we didn't take ours," he said. "When you see the clip, and Scott is very disappointed, the ground he made up to get there was pleasing.
"He is bitterly disappointed as that was a straightforward chance really, it was an open goal seven yards out, but I was pleased he got there and if he keeps getting in there the goals will come."
