Mikel Arteta has spoken after Saturday's defeat at Chelsea:

on a difficult day…It's not good enough with the way we started the game. Just before they scored we had a chance with Olivier that could have changed the game completely but we gave them the game in [their] hands.

If you give the ball away in the middle of the park against Chelsea you know what's going to happen. That's what we have to avoid and we knew that from the start of the game and we haven't done it. We paid for our own mistakes. We have to take it on the chin because it's unacceptable to lose another big game like this.

on being concerned about the big games…The first one [at Manchester City] you may analyse in a different way, the second one [at Liverpool] was a bit different in the way we conceded the first three goals but on Saturday in my opinion it was worse because it was more our fault. It was when we were in possession of the ball and we knew that we couldn't take risks in certain areas. After 3-0 and with a man down it makes it impossible.

"You cannot only just move on, you have to analyse what you've done and react. I'm expecting a big reaction on Tuesday... Saturday was not good enough for this football club"

The good thing is we have a lot of things to play for and we've 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's unacceptable.

on two home games coming up…Yes but we have to take [on board] some of the things we have done wrong. You cannot only just move on, you have to analyse what you've done and react. I'm expecting a big reaction on Tuesday because we have to and Saturday was not good enough for this football club.

The pressure we put on ourselves by losing games like that is massive and there's no need for it. We just disrupted the good season we were having. I don't know what else to say apart from sorry to everyone at the club, the fans, and we promise that we will try hard to put that right.

on the title race…This can change at any moment. There are two midweek games again and it can change quickly around. We just need to be there again because if there's any possibilities we have to be able to take it. Let's try again, it's been a difficult day but we need to stay together again and battle because what we can still get is very good.

on the players feeling the pain…It hurts deeply inside. It's embarrassing to be on a football pitch in that situation. Psychologically it's 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.
