Wojciech Szczesny may have come a long way in a short time, but the Arsenal keeper insists he still has plenty to learn.
The Poland international has seized his chance to become the Gunners' number one and will be looking to maintain impressive form as Arsenal aim to secure safe passage into the knockout stages of the Champions League with victory over Borussia Dortmund tonight.
It was not that long ago that Szczesny was on loan at League One Brentford before inconsistent displays by Manuel Almunia and Lukasz Fabianski saw him handed a first-team chance.
There is no doubt Szczesny has the confidence to succeed at the highest level, but despite such a positive personality, the 21-year-old accepts more lessons lie ahead.
“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 will keep working hard and doing my best. I am satisfied, but you can always be 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 next day, 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.”
Arsenal recorded a fifth straight Premier League win when they beat Norwich 2-1 at Carrow Road on Saturday to move within striking distance of the top four.
It is some turnaround in fortunes following an appalling start to the season, which saw the Gunners slump to 17th.
Szczesny continued: “I feel the improvement. We work on the training ground and it seems to be working during the games.
“We are much more confident, we concede less goals and I hope we can keep it going.”
Arsene Wenger feels Szczesny's career is heading in the right direction.
The Arsenal boss said: “He has done extremely well. What is very positive is that there is a lot more (to come).
“He works hard in training to improve, is focused and humble, so like the rest of the team I think he has a good attitude and a good spirit.”
Victory tonight would see Arsenal qualify with a match to spare, although not necessarily at the top of Group F.
