Wenger's men were booed off Emirates Stadium after a poor first half in which they created next to nothing, before again failing to find their feet after the break as Michu netted a late brace.

The victory sees Swansea jump above the north London outfit on the English Premier League table as they move up to seventh, with Arsenal falling to 10th.

The Frenchman gave the visitors credit while slamming his own players for conceding two late goals, but did suggest his side may have been suffering after their European exertions.

"We were not good and Swansea deserved to win," Wenger told reporters. "We looked very jaded after two away games in the Champions League.

"Where we were guilty was with three minutes to go at 0-0, if you cannot win you must not lose.

"I believed we tried very hard to get back into the game, but we weren't sharp enough. We didn't create enough chances, we will work on it."

With the home supporters making their feelings known throughout – and after – the game, the 63-year-old said their displeasure was justified.

"Our fans cannot be happy when we do not win games and what we produced today is not enough to keep our fans happy," Wenger said.

However, when directly questioned about the fans' protest about the direction the club was heading in before the match, he replied: "I don't want to get involved in that."

Swansea manager Michael Laudrup was pleased with his side's display, with his players solid at the back and then Michu on hand to deliver the killer blows late on.

The Dane said the bigger games were easier to mentally prepare for, while he praised his players for recording three good results in a week.

"I knew we would play well against the big teams, it is easy to motivate yourselves for those games," Laudrup said.

"Seven points from three matches – away to Liverpool, against the season's surprise so far in West Brom and now away to Arsenal – is a fantastic week for us."
