However, the Germany international did not make his Premier League debut at the weekend against Manchester City as it was instead veteran stopper Petr Cech who got the nod, with a turbulent performance across the 90 minutes.
That has led many to question who exactly is first-choice for the Gunners this season and Arsenal legend Jens Lehmann has given his view on the debate, suggesting that his compatriot may need to show more in training to be handed a starting spot.
“Arsenal is a big club. It’s a different style of game, a different expectation, and obviously a different competition. Sometimes these guys aren’t used to that competition.
“I don’t know how he’s doing in training, but it tells you something if a guy who cost £20m, and has been chosen by the new manager, is not playing. That’s the strength of the squad, a misjudgement probably, but no-one knows because we are not there in training.
“We don’t know who the coaches like. If he tries a new player out, if not the other guy is playing. Bernd is a good ‘keeper, no doubt about that. The question is: can he show more than he did in the past? He must take more risks and continue his development. If he does that – good!”
