I'm glad Cazorla is going. Loved him as a player, but he was another long term injury that Wenger insisted on carrying. Wenger leaves, Cazorla goes too. If Wenger had stayed, Cazorla would have stayed and probably spent most of the season in the treatment room again.
I think it's a positive (as in sane, sensible and what every other club somehow already figured out) not to be carrying fundamentally unfit players. It could be pure coincidence, but it also might be another one of Wenger's fatherly policies being binned. Then again, we're keeping Jack, another player who can't seem to make it through a season.
