Mertesacker, who has played alongside Ozil for club and country, is convinced that Wenger will get the best out of the 24-year-old and make him a Premier League success story.
After helping Germany to a 3-0 victory over Austria on Friday, the towering centre-half said: "I know him quite well. We spent two years together at Werder Bremen so I think that Arsene Wenger will get the best out of him.
"I think he will fit in. He suits us and we're really looking forward to playing with him and to be his team-mate."
