Mamelodi sundowns co coach manqoba mngqithi warns ronwen williams

I think there may be some confusion here!

Mamelodi Sundowns has a single head coach, not a co-coach. The current head coach of Mamelodi Sundowns is Rulani Mokwena, not Manqoba Mngqithi. Manqoba Mngqithi is actually the assistant coach of the South African national team, Bafana Bafana.

So, it's unlikely that Manqoba Mngqithi would be warning Ronwen Williams, as he is not involved with Mamelodi Sundowns.

If you meant to ask about a different coach or player, please feel free to clarify!
