The former Bayer Leverkusen goalkeeper signed for the Gunners yesterday.
He told Arsenal Player: "Of course Arsene Wenger was always the coach at Arsenal but now it's a new chapter for the club. I spoke to Unai Emery and he said that he believes I'm a good goalkeeper, and that he wanted me to join. For me it was clear that the club and the coach wanted to sign me, so I'm happy that all the people at the club said that I'm a good goalkeeper.
"I was excited and proud too, because Arsenal is such a big club all over the world. In Germany, Arsenal are so famous and when I heard it, I was a little bit nervous but at that moment it was clear for me: I wanted to sign for Arsenal."
Leno also named dropped Jens Lehmann, who left the Gunners yesterday as coach firing a barb at the club as he departed.
"I remember many things, like Thierry Henry, Jens Lehmann, Highbury and Alexander Hleb too," said Leno. "I remember him at Stuttgart and then he played at Arsenal. For me, it's the same story now. There are so many things that I can remember of Arsenal."
