When you a buy a player like Ozil, you know his strengths and Arsene Wenger knows, I think, where he is at his best.
Arsenal needs Arsene Wenger, but also Arsene Wenger needs Arsenal. For me, he will die at Arsenal. He is like Sir Alex Ferguson at Manchester United. After you think about Ferguson and United, you then think about Wenger and Arsenal.
Wenger is a top manager, he has shown that unbelievably. The thing I like is this manager can make an average player one of the best players in the world.
I remember Arsene Wenger very well from our time in Japan. I like the way his teams play, with an offensive mentality - it is a philosophy I share. I think he gets the best out of the players he has, and this is the key to his success.
All that I can say is that, from my point of view, our manager Arsene Wenger is an unbelievable man off the pitch and as a manager.
Arsenal have a great manager in Arsene Wenger, top quality players and an attractive style of play. These were all important factors in me choosing to sign for Arsenal.
Arsene knows what he wants and knows how to get the best out of you - that is why he gets such an impressive response from his players.
If you gave Arsene Wenger eleven players and told him to pick his team, this would be it.
Arsene Wenger was always the kind of manager whose belief in his team's qualities was steady as a rock and who approached matters with never-ending patience.
Yes, I met with Arsene Wenger, who is a great coach. He has a great reputation here in France, he's well-respected and knows how to develop young players.
I was fortunate to play under Thomas Schaaf at Bremen. And I played for Arsene Wenger. So I always felt, let's say, more responsible than others towards the manager and his succession.
When I told Arsene Wenger I was leaving, he said to me, 'I have £25m to spend on a few players.' My answer was, 'Obviously, Mr. Wenger, you are not shopping in Harrods. That will only buy you one good player.' Now I have been proved right.
When you are young, you always want to improve, to work with great managers - and Arsene Wenger is one of the best in the world.
Arsene Wenger is just an unbelievable manager. I think he's a tremendous person, and he is just as good as there is. You can't judge a manager on one game or on one stretch of games. You judge him over time.
Why did I not join one of the top five clubs in Europe? Because I am no longer one of the top five players around, and neither are Inter among the five best clubs.
Arsene Wenger has not just brought success to Arsenal. He is a very creative manager, producing almost fantasy football.
