Arsenal boss Arsene Wenger says their top four consistency is proof of a successful transfer policy.

Wenger has defended Arsenal's ambition as the Robin van Persie saga dragged on.

"We are now 15 years on the trot in the Champions League and I believe that shows that our model works.

"On the other hand we are very ambitious, we want as well to win trophies.

"It's not enough just to be in the Champions League and we are focused on that of course.

"We work very hard to make the team stronger. In this job, when you have consistency in your attitude you can stay at a certain level.

"The most difficult thing is to be consistent and we have shown over the last 15 years that we can maintain that consistency.

"I am confident that we have to be faithful to what we believe is right in football and in the game - the way we play football."
