Watch al ahly dump mamelodi sundowns out of caf champions league

I think there may be some confusion here!

Al Ahly is an Egyptian football club that plays in the CAF Champions League, while Mamelodi Sundowns is a South African football club that also plays in the CAF Champions League. However, I'm not aware of any specific match between the two teams where Al Ahly "dumped" Mamelodi Sundowns out of the competition.

If you're referring to a specific match or tournament, could you please provide more context or details? I'd be happy to help you with any questions or information you may need!
