Wojciech Szczesny may have seized his chance to become Arsenalâ€™s number one, but the Polish international is well aware he still has a lot to learn.
"I still need to prove myself at this club, to work hard every day and prove myself as a number one," said Szczesny, who insists the last-minute mix-up at Wembley which cost Arsenal the chance of Carling Cup glory in February is very much in the past.
"I am going to keep working hard and doing my best. I am satisfied, but you can always be much better.
"I can improve on every single aspect of my game. There is no finished article in football. I am only 21, so I try to improve every aspect.
"I am just focusing on doing my job properly and if my manager and team-mates appreciate it, then I am happy."
Szczesny added: "People still say I am over confident, but I am a big critic of myself.
"If I watch a game the day after I played it, I look at the mistakes I have made and I try to learn from them.
"I speak to the coaches and we analyse every little mistake and it's all to make me improve.
"There is a lot of room for improvement, I believe."
