So change just for change's sake? I don't see the point in that to be honest. If they can get a good manager from one of the big leagues, such as Simeone or Tuchel then fair enough, I guess. But to get rid of Wenger just to change things up seems ludicrous to me.
Wenger has them failing in the exact same way every season, no other club serious about trying to win trophies would put up with this not for 10 years of failure.
