Manager Arsene Wenger accepted Arsenal had only themselves to blame after throwing away a two-goal lead for the second time in a week as Fulham battled to a 3-3 draw at the Emirates Stadium.
Early goals from Olivier Giroud and Lukas Podolski put the Gunners in control, just as they had been in their Champions League game at Schalke on Tuesday night, only for the Germans to fight back.
It was a similar story again this afternoon as Fulham rallied after Dimitar Berbatov reduced the deficit and it was no surprise when Alex Kacaniklic levelled before half-time.
The visitors then went ahead from the penalty spot when Berbatov slotted home after Mikel Arteta had fouled Brian Ruiz.
Although Giroud quickly levelled at 3-3, the Gunners could not find a winner - but were then awarded a penalty in stoppage-time for handball, only for Fulham keeper Mark Schwarzer to produce a brilliant stop from Arteta's low effort.
"It was frustrating because we had the opportunities to win. We were caught in a bit too comfortable of a position because we did the most difficult thing - we scored two goals to go 2-0 up. At that moment we lacked urgency defensively," said Wenger.
"In the second half we gave absolutely everything and I have to give credit to the players, in the last three games what they have done physically is amazing.
"Even at 3-2 down we didn't give up and continued to go forward and we had the chances to win the game."
Wenger, though, refused to lambast vice-captain Arteta for not dispatching the last-gasp spot-kick.
"You cannot blame Arteta for that. It is part of the game. Who hasn't missed a penalty?" the Arsenal boss said.
"The positives are that we can score goals now. The negatives are to concede three goals at home of course, and the chances we gave away, defensively it wasn't an historical performance."
Wenger added: "I feel where we are most guilty is on the corner [for the first Fulham goal] because you are 2-0 up, it can happen with Berbatov who is good, he can create chances - but nobody jumped for the ball at all, we just let them score the goal."
Wenger denied Arsenal were suffering from a lack of confidence.
He said: "We had physically some moments in the game today that you could see we have played three tough games - we played Saturday, Tuesday and we needed a little breather.
"Some players were a bit jaded before the game, they gave it their all today - but Fulham are good going forward."
Cottagers boss Martin Jol admitted he had "so many mixed feelings" about the final result of such a dramatic encounter.
"We played some fantastic stuff," he said. "Before the game we said we would try to dominate them which is hard here, but we managed that."
"I can't remember being 2-0 down - especially here - then being 3-2 ahead and we could have scored two or three goals after that.
"I really thought this could be the first time ever to beat them away, but in the end it was not to be.
"However, if you concede a penalty in the last 20 seconds and then still do not lose, maybe we should be pleased in hindsight."
Jol felt Arsenal substitute Andrey Arshavin had been very clever in the way he engineered Arsenal's stoppage-time penalty, drilling his cross against Sascha Riether's arm which was enough for referee Phil Dowd to point to the spot.
"I think he did it on purpose," said the Dutch coach. "There was no way to cross it. Did he have a shot, no? There was no room to cross. It was ball to hand.
"I have had a few fantastic players in the past and they could do it as well, and the ref falls for it.
"I think the ref was pleased as well not to see it go in because it would have been harsh."
