Arsenal boss Arsene Wenger criticised a lack of discipline and focus from his players after Sunday's stunning 3-2 defeat at Wigan Athletic effectively ended their already slim Premier League title hopes.
Charles N'Zogbia's late winner in a 3-2 success for the Latics effectively sounded the death knell on the Gunners' title hopes.
The former Newcastle winger curled home a stoppage-time winner to seal a famous comeback for the Latics, who had entered the final ten minutes of the game at the DW Stadium two goals down.
Goals in either half from Theo Walcott and Mikael Silvestre looked to have secured the points for Wenger's men, only for Ben Watson and Titus Bramble to haul Wigan level.
And just when the drama looked to have ended, N'Zogbia clinched a famous win from the edge of the box.
Arsenal are now six points behind leaders Chelsea with just three league games remaining in the season.
"All I know is if we had won today then we would have been back in it," said Wenger.
"I believe we were not focused, not disciplined and were caught.
"In football you have to stay focused for 90 minutes, otherwise you run the risk of being punished.
"That is especially the case against a team with nothing to lose, fighting not to go down. You knew they would not give up, and in the end we were punished for that."
Wenger has admitted that a more pressing concern is now holding onto third place in the table and avoiding the Champions League qualifying round game that the fourth placed team must safely navigate.
"My target is to win the next game," he added. "Manchester City and Spurs can still catch us, so we have to win at least one of our remaining games."
