Arsène Wenger says Wojciech Szczesny has the “aggressive focus” all great goalkeepers require.

The 21-year-old has been a revelation since breaking into the Arsenal first team in December 2010 and has developed into one of the best goalkeepers in the Premier League.

Szczesny has proved a confident figure between the posts for the Gunners, but Wenger says the Pole’s focus is equally as important.

“It is good that he has confidence - you feel that when he stands in goal. But as well it is a good mixture between confidence and concentration,” he said.

“I believe a goalkeeper needs an aggressive focus. When I say that I mean a concentration that is ready to fight. If you lose that then you are always in trouble because you need to be so sharp in every reaction you show.

“If you lose a little bit of that committed focus then you are caught. You touch the ball but you don't save it, and for that you need the right mixture between confidence and focus.”

While Wenger admires Szczesny's confidence, he says it must be managed.

"Life teaches you things; that you always have to be focused, that when you are younger you think too quickly that you have made it. It's [something] to prove every day," he said.

"That's why it is important to analyse people well. Confidence is a massive quality he has but you have to manage it well without losing your focus."
