Yes, I'm Done With Nigerian Football and NFF; Siasia Resigns As Nigeria U-23 Coach

Too many blunders from the managers of sports in Nigeria in recent times...
Samson Siasia has resigned as the coach of Nigeria’s U-23 football team due to what he describes as “a disrespectful system”.

Siasia, the most decorated African coach at the Rio-Olympics, having also won a silver medal in Beijing in 2008, claims to have gone unpaid for five months by the Nigeria Football Federation.

He confirmed that he had quit Nigeria football after "a turbulent and incredible campaign in Brazil."
