Sundowns blunt golden arrows to dethrone orlando pirates

I think there may be a few issues with your statement!

Mamelodi Sundowns is a South African football club that plays in the Premier Soccer League (PSL), while Golden Arrows is also a South African football club that plays in the PSL. Orlando Pirates is another South African football club that plays in the PSL.

However, I'm not aware of any recent match between Sundowns and Golden Arrows where Sundowns "blunted" Golden Arrows to dethrone Orlando Pirates. It's possible that you may be referring to a specific match or tournament, but without more context, it's difficult for me to provide a accurate response.

If you could provide more information or clarify what you mean by "blunt" and "dethrone", I'd be happy to try and help you with your question!
