Unai Emery admits Arsenal must improve their passing out from the back for Thursday's Europa League clash with Eintracht Frankfurt.
The Gunners' sloppy distribution against Watford on Saturday saw them blow a two-goal lead to settle for a draw.
And Emery is expecting similar high pressure from Frankfurt on Thursday.
"To learn is first to have analysis on how we can improve, how we can recover our confidence playing with our objectives, starting and controlling the match, what we are doing with the ball.
"Really on Sunday we needed more, that's what we wanted. We made some mistakes and conceded some goals.
"We spoke and we are working yesterday and today on how we can play tomorrow. Frankfurt are usually doing a very high press, with very fast players around the opponents.
"Tomorrow we need to improve on the mistakes we made on Sunday to do better. Also we want to achieve another way on the pitch, how we can break the pressing.
"After we want to control every game with the ball, with the positioning. We did that on Sunday in the first half, but in the second half we didn't. And tomorrow is a new challenge, how we are improving, our positioning, our control and our ability to break the press.
"Also how we can play the long ball and make some actions in the attacking third, to get the ball, to score and to win the match. Tomorrow is another challenge for us to show we can improve from the game on Sunday."
