Van Persie struggling with new Arsenal system
He said: "I don't feel that I'm at the top of my game as a main striker yet. I have to improve on many things but it is quite new and the main thing is that the boss really backs me on this one.
"He really thinks I can succeed as he has a lot of trust in me. I will do my best to play as many games for the team. Personally, when you get a chance you want to score. When you don't score you are not happy with yourself but the first thing for me is that we win games and I can give assists and help the team.
"If I have a chance I should score and I need to score. I'm confident it will be okay very soon."
