Speaking to Sky Sports post-match, Arteta said: "Very tough to accept it. In the second half we did not perform in the way we should and the way we require to win a Premier League match. It is better not to judge it, we are all too emotional about it. You have to take the hit because we deserve it.
"It is very easy with emotion to say things that can damage the team. Everyone wants to do their best. You have to go through tough periods. Today at the last minute, we paid the price. We have to do basic things much better than we have done.
"Today we need to accept it. We need to be critical of ourselves because it was not good enough. In the league, it is the reality that we have not been consistent over the last few months. You have to stand up. When you have a moment of difficulty, we have to show how much we want it and how good we are. We have to stand up."
