It's time for Arsene to step aside and for a new talent to come in and take his place.
Arsenal don't have what's close to be a Premiership winning team which is what they should be aiming for. They have lots of talented players, however it's time for a new approach to move the club forward.
If you take the view that Arsenal are a selling club which develops world class players and then allows them to move on at a profit and are happy for that then keep Wenger.
However if you want to challenge for titles he really has to go.
