Ex kaizer chiefs striker moon had no beef with middendorp
I think there may be some confusion here!
Kaizer Chiefs is a South African professional soccer club, and I'm not aware of a striker named "Moon" who played for the team. Additionally, Ernst Middendorp is a German football manager who has managed several teams, including Kaizer Chiefs, but I'm not aware of any specific controversy or "beef" between him and a player named Moon.
If you could provide more context or clarify who Moon is, I'd be happy to try and help you further!
