New boss Unai Emery has stuck with veteran goalkeeper Petr Cech so far this campaign despite the German’s £22.5m transfer to North London.
However, Leno is not worried about his lack of playing time and backs his own ability to force his way into Emery’s plans.
He told Sport Bild: “I am convinced that my change was the right decision.
“I’m not crazy. It may take a few weeks or months, but my time here will come.”
Leno did not make the final 23-man Germany squad who were knocked at the group stage of the World Cup in Russia for the first time in Der Mannschaft’s history.
Cech has started all three Premier League games for Arsenal so far this term, conceding six goals in the process.
He has struggled to reproduce the form that he consistently did for Chelsea during his 11 years at Stamford Bridge.
However, Emery has stuck with him, despite almost scoring the most calamitous of own-goals in the opening weekend fixture against Manchester City, and so far has been unable to plug the leaks in Arsenal’s defence.
Leno appeared in pre-season but has since found himself behind Cech in the pecking order, but he believes that with patience he will start to see game time with the Gunners.
