Arsenal captain Mikel Arteta says they have only themselves to blame after defeat to Manchester United.
Arteta was left perplexed as to why his side had been unable to convert such a dominant first-half display into a positive result.
"We will have to analyse what we did wrong to lose the game, but if we played 10 times like this against Man United, then we would win nine and draw one," the Spaniard said.
"The atmosphere the fans created was one of the best we have had here this season.
"They have seen both the quality and the determination which the team played with, so we say sorry, we tried our best, but it was not our day - (next time, the team) just have to put the ball in the net."
