The 24-year-old sealed a €50 million deadline day move to the Emirates from Real Madrid after falling down the Santiago Bernabeu pecking order.
While the legendary striker acknowledges that the former Werder Bremen star has moved to a less glamorous club, he feels the switch will prove invaluable with the 2014 World Cup looming.
"I'm happy for Mesut that he has found a great club, even when Arsenal might be not as shiny as Real is. He will develop there and take more responsibilities," he said at a press conference.
"It's an important step for him, especially in a World Cup year. In today's football world, everything moves fast. When a new coach arrives, a lot of things change.
"This is no drama, it's usual business. If such a club as Arsenal and such a coach as Arsene Wenger want you, no matter what, it gives you a confidence boost."
Ozil is set to make his debut for Arsenal against Sunderland following an international break which should see him feature against Austria and Faroe Islands
