The Pole silenced calls for boss Arsene Wenger to go out and sign a new goalkeeper when he broke into the first team in January 2011, stringing together a series of impressive performances.
But a number of high-profile errors in the second half of last season, combined with a shaky Euro 2012 with Poland, have dented Szczesny's blooming reputation, and he admits he needs to work on his concentration.
"My biggest problem is not enough focus in the games without huge stakes. I can't find the spark in myself," Szczesny told The People.
Szczesny is eager to improve this side of his game, as he wishes to remain with the North London side for the rest of his career.

Currently Szszesny is the undisputed No.1 keeper on the books at the Emirates, and the 22-year-old is determined to write his name into the history books at the club, in much the same way as Paul Scholes and Paolo Maldini have done at Manchester United and AC Milan respectively.
"I dream of a similar scenario. I hope that when we sit down to have a chat 14 years from now it will be about my two decades at Arsenal."
"That was the moment I was very much needed. It made me realise that I'm not only a good keeper, but I can have a big say on how we perform."
