The Arsenal boss spoke to BT Sport after the match: "Really happy with the win, six points now and a clean sheet.
"But in general I think we lacked a bit of connection today between the players; too many simple things, too many giveaways. We've weren't that consistent and that dominant throughout the game.
"There were eight changes (from Saturday's win vs Tottenham). You can feel that. A lot of players haven't played a lot of minutes and you could feel that in their understanding what to do and when to do it. That timing was missing. But attitude-wise, no issues.
"In the final third we looked very dangerous... The goals we scored were good goals."
On bringing in Saka, Jesus, and Odegaard early in the second half: "A few players, you could see they had a different intensity, not enough exposure, enough minutes, so we had to make changes."
