He told Die Welt: "Arsenal is one of the best 11, 12 teams in Europe and now he gets the chance to take responsibility.
"At Real, it was so that [Sergio] Ramos and [Cristiano] Ronaldo called the shots. Now Mesut can assume such a role in London. He is now catapulted into the role of a leader.

Ozil could make his Arsenal debut on Saturday when the Gunners visit Sunderland in the Premier League.
