Arsenal boss Mikel Arteta was delighted with their 2-0 win at Newcastle.
Mohamed Elneny scored his first Premier League goal for the Gunners, before Pierre-Emerick Aubameyang secured the points in the second half.
Arteta said, "This game showed our focus is still there in the Premier League. We believe that anything is possible if you're picking up points and we wanted to put bad results out of the way.
"We had a great attitude, some moments of real quality and had total control from the start.
"We refreshed the team because we've played so many games. Thursday was very demanding but the team was really committed and focussed on this game and that's why we won.
"We controlled the game and we accelerated it when we needed to. The early goal gave us confidence which we needed after the defeat on Thursday.
"We have to do as well as we can and finish as high as we can."
"You need big performances and we had that today."
On David Luiz's injury, he added: "It's incredible the amount of injuries we've had. We're losing big players.
"It's a shame because David had made a big effort."
