Simba sc leave it late to defeat relegation threatened kmc

I think there may be a few issues with this sentence!

Firstly, Simba SC is a football club from Tanzania, not a team that plays in a league with KMC (which I assume is a different team).

Secondly, "sc" is not a common abbreviation for a football team, and it's not clear what it stands for.

Lastly, "leave it late" is a phrase often used to describe a team scoring a goal in the dying minutes of a match, but it's not a common way to describe a team's overall performance throughout a season.

If you meant to say something else, please feel free to rephrase and I'll do my best to help!
