Wenger has worked with some pretty useful players during his glittering managerial career - but how many of them have been genuinely two-footed? Dennis Bergkamp, George Weah, Thierry Henry or Jurgen Klinsmann, maybe?
"Glenn Hoddle was like that - you could not say if he was left or right footed," said Wenger.
"And Santi Cazorla is similar on that front - I don't remember anyone else I have worked with who was two-footed as much as those two.
"Santi is right footed but when you watch him play you don't know. It shows how important that is in the modern midfield.
"Right or left foot was always important, but we forget about it sometimes. I'm surprised there are not more."
