Arsenal boss Mikel Arteta on ITV: "We're disappointed. We could have got much more from the game but an action decided a game that was really tight and competitive. Unfortunately we are out.
"We had quite a lot of control in the second half and we had big situations we didn't put them away and in those games you need to do that.
"We can take a lot of positives. I think the way we approached the game and the way we competed in the game was really good because it's very tough to do that against this incredible team and we played face-to-face with them."
Asked what they need to learn from this game, he said: "In the big moments in big matches you have to make the difference and that's how you win against these teams."
