Former Arsenal captain Robin van Persie has taken a swipe at manager Unai Emery.
Van Persie says he can't work out the style of play Emery wants to employ.
He said, "The Wenger teams were always used to playing football based on his philosophy.
"You can see the same thing happening with Jrgen Klopp and Josep Guardiola at Liverpool and Manchester City, respectively. But with Emery I don't really see his philosophy. What exactly is his philosophy?
"It seems to me that he is always adapting his playing style to the opponent. For me, it is true that you are basically based on your own qualities."
