A frustrated Arsene Wenger said Arsenal made too many "bad decisions" towards the end of the 3-3 draw at Liverpool, costing his team the victory.
Liverpool equalised in the 90th minute through Joe Allen to cap a frenetic game that saw the Gunners come from behind twice and take the lead through Olivier Giroud's second goal of the night.
Wenger felt his team should have taken their chances to score a fourth to kill off the game.
"I feel that at 3-2 we are guilty of two or three bad decisions in the final third where we try to play not together enough, and in the end we got caught on the long ball," Wenger told BT Sport.
"Of course it's always frustrating when it's 89 minutes and you get caught on such a simple ball. That's where we have to look at ourselves, that should not happen."
Theo Walcott sent a tame shot wide on a counterattack when he had a chance to feed Joel Campbell and Wenger said Giroud also should have done better on a couple of occasions near the end.
It was the second year in a row that Arsenal conceded a last-gasp equaliser at Anfield and the Gunners missed a chance to widen the gap to main title rival Manchester City, who were held 0-0 by Everton. Arsenal are now level on points atop the Premier League table with Leicester, who beat Tottenham 1-0.
"It's unfortunate, but overall you cannot fault both teams for giving absolutely everything," Wenger said.
In a frantic first half, the teams exchanged four goals in a 15-minute span, with Giroud then missing a wide-open net from close range and Roberto Firmino denied a hat trick by the crossbar before the interval.
Giroud then scored what had seemed like the winner with an exquisite finish in the 55th minute, but Arsenal couldn't hang on in the driving rain at Anfield.
"It was a nice game for the fans, because it had a lot of intensity, a lot of chances to score. But when you concede three goals in an away game it's hard to win," Giroud said.
"So we should have been stronger until the end because we did well in the second half. My first feeling is disappointment, but we have shown some character to come back here when we were 1-0 and 2-1 down."
