Arsenal boss Mikel Arteta was disappointed with Manchester City's winner in Friday night's FA Cup defeat.
City won 1-0 thanks to Nathan Ake's effort.
Arteta later said, "Really disappointed. I think we could have got much more out of the game. The action decided the game but it was a tight game and that one action changed it all. I think we could have dealt with it much better in terms of our discipline when the ball was in the box.
"We had big situations in the game and we didn't put them away. We can take a lot of positives, I think the way we approached the game and competed. It is really difficult to win against this team but we went head to head with them.
"In the big moments, in big matches you have the make the difference. That is how you win these games."
