Aston Villa 0-2 Arsenal: What Arteta said
Arsenal boss Mikel Arteta has been speaking to BBC Radio 5 Live following the win: "We had to change momentum. We had a 10-minute gap when we didn't get the rhythm and they were on top.
"They had the big chance when David [Raya] made an unbelievable save and it is was the magic moment of the game. I gave his moment to him [Leandro Trossard] to control the game."
On goalkeeper David Raya: "We conceded really little and it is a big credit to the team, as it is a difficult place to come, but when we needed him he was there and he made a terrific save."
On Bukayo Saka and his team-mates: "Not just him [Saka], but everybody played with a lot of personality. Aston Villa had a defensive approach, more than what we expected, but we adapted and the team played with a lot of courage.
"Again, when you need individuals, they stood up and they made themselves count - that is why we won the game."
On the psychological benefits of beating Aston Villa: "The two previous performances [against Aston Villa], on paper, you have to win comfortably. But we didn't, so there was something missing. Today, we did it - with a bit of luck and individual performances, we managed to win the game."
