And the minute he walked through the door of the old Highbury, he realised just how much homework Arsene Wenger had done. The Arsenal boss handed Van Persie the dossier which helped him decide to fork out £2.75million for the striker.
The player said: "Arsenal had watched me in over 40 matches.
"I couldn't believe what I read. They had written down every detail. Like how many times I went forward or if I came back to defend or if I shot at goal.
"This didn't just cover normal games or friendly matches but also what I had done during training sessions.
"When I had my first meeting with Arsene Wenger, he knew far more about me than I knew about him.
"He mapped out my future and I'm now exactly where I should be and fully on course. In the last two years at Arsenal, I've completely changed.
"The only thing that I strive for is to become better.
"I've set high standards for myself. Recently I missed a penalty and one could say that even the really great players have missed them. But I cannot accept that excuse. With my technique, it should definitely always be a goal."
