Asked about his thoughts on Raya's mistake, Arteta said: "I don’t like the principles that we apply in that moment and the orientation of the ball. I was praying [we would hold on]. It was a really emotional game. A great team to play against. 3-0 up you’re in control and then an individual error happens that clicks something. We started to deal with the situation better, but they have the players to put a lot of courage forward."
He added to BBC Match of the Day: "We gave it away and made a huge mistake, but the reaction from my players [was good]. David Raya stood up and took six-to-seven crosses and that is what we want and if you are going to take risks you have that reaction - I am really proud of them [players].
“[Playing out from the back] is worth it depending on the game context. That error is not bad luck it is execution and the moment before that the picture was not what we wanted it."
