Arsenal boss Unai Emery says a tough schedule was reason for their slow start to the season.
The Gunners host Leicester City on Monday aiming to win a tenth consecutive game.
When asked about the reasons behind the upturn in results, Emery said: "I think the first thing is the opposition.
"Their qualities and performances are very, very high. But also we are doing things our way and we improving our things.
"We need to carry on to find our best individual and collective performance to stay close to them. But I say to you, we need to get better in a lot of things now. It is our best target now: don't stop. We need to think and analyse with the players to improve."
