Wenger is keen on signing an experienced goalkeeper this summer.
But the shot-stopper insists: "My confidence never gets crushed.
"Whatever happens, my attitude doesn't change. I still try my very best in training. I want to make sure I'm in the best shape possible. Whether someone comes in, it's not really my decision and it won't affect me in any way. You have to deal with the competition.
"I think that the competition from Lukasz when he was fit was pretty tough and I enjoyed it. I really don't mind competition, it can only bring the best out of me. I don't doubt myself. There is the same talk every year and no-one has been brought in. I think the manager has shown enough faith in me to make me feel confident in my own abilities.
"It's not really my business if he signs anyone or not. I let him make his decisions and whatever happens, happens. I'm not really interested in that."
