Arsenal manager Arsene Wenger blamed complacency for their second Premier League defeat of the season against Swansea.
The Gunners desperately needed to bounce back after the mid-week fiasco against Anderlecht in the Champions League but two goals in three minutes from Gylfi Sigurdsson and Bafetimbi Gomis leave Wenger's side outside the top four ahead of the international break.
"It's disappointing to throw a game away like we did," Wenger told BBC Sport.
"We were 1-0 up and had to be tight defensively and wait for that second chance. But you have to credit Swansea who didn't give up.
"Football you can believe anything is possible, any minute you can concede.
"Bafetimbi Gomis is good in the air and it can happen. You have to accept that Swansea will fight until the last minute. We eased off at 1-0 and let them back into the game.
"Football is down to performances. People can say what they want. We are here to produce performances, and didn't do that right until the end of the game."
