Arsenal boss Mikel Arteta was happy with victory at Leeds.
Bukayo Saka struck for the Gunners as Patrick Bamford failed from the spot for Leeds.
Arteta said: "It's always very hectic here. I think it's not a coincidence winning like this. What the team shows, the character it shows, the personality it shows, the desire to play. There are players that are really struggling after Thursday night. To go from Thursday night in Norway and then come to Leeds and win both games the way we have done - big credit to the boys. It shows a lot about the team.
"It's always really tough coming here, when you see the results that happened here earlier in the season. So again, extremely happy because we keep winning, and you have to be able to win in any context. And you know, it was very different today, and we found a way to win it.
"We left the game open and from the beginning - from the first whistle in the second half we started not at the rhythm, not making the right decisions time after time. We put ourselves in big trouble. But then when you get into those moments, I love the resilience, the fight the character and the courage the team showed to win the game."
