Arsenal midfielder Mikel Arteta publicly apologised for their dismal show against Chelsea last Saturday. Arsenal lost 6-0 at Stamford Bridge.
He has vowed that they would get things right when Swansea visit the Emirates Stadium on Tuesday night.
He said: “We paid for our own mistakes. We have to take it on the chin because it is unacceptable to lose another big game like this.
“You cannot only just move on, you have to analyse what you have done and react. I am expecting a big reaction on Tuesday [because] Saturday was not good enough for this football club.
“The good thing is we have a lot of things to play for and we have always reacted to disappointments and difficult moments, but this one is a really hard one to take, it was a massive game for us and for me it is unacceptable.
“The pressure we put on ourselves by losing games like that is massive and there is no need for it.
Arteta could not deny that the Gunners were not good enough and have no option but to raise performance levels against the Swans, with the squad having held a debrief session at their London Colney training base on Sunday.
He further said:
“It hurts deeply inside. It is embarrassing to be on a football pitch in that situation,” he said.
“Psychologically it is really hard, and when you go through that you analyse it and you know you don’t want to be in that situation again.
“I promise everyone that we have that hunger to put it right. On Tuesday, we have an opportunity again at home and we just need to bounce back.”
The heavy defeat against their city rivals spoiled Arsene Wenger’s 1000th match as Arsenal manager.
