Szczesny hopes both he and the club can end a frustrating season on a high.
He said: "I know that Arsenal should not play as badly. We're not even through March and we have lost everything. We have only nine games to save the club and not humiliate ourselves.
"Arsenal have been in the Champions League for the past 16 years and it would be horrible not to qualify this time.
"Those are our most important games in our careers. It's our hardest time since I got here."
