Samson Siasia, Nigeria’s former under-23 coach, has given the Nigeria Football Federation (NFF) a two-week ultimatum to settle its debt to him.
Siasia says the NFF owes him five months’ salary arrears from the start of April to August 2016.
The 49-year-old led the country to a bronze medal finish at the Rio Olympics.
“The national team is preparing for a World Cup qualifier and to be honest my unhealthy distractions are the last thing they need right now.
“I’ve made it clear in my letter that my assistants and I should be paid the backlog owed because it’s inhuman.
“As head of our families we sacrificed everything for the country but the NFF refused to pay us – it’s not only heartless but wicked,” he said.
A top NFF official acknowledged the debt but said Siasia’s latest remarks are “unfortunate”.
The NFF attributed the delay to the latest financial procedures which must be adhered to by all.
“There’s a new financial procedure in place, which has not been concluded by the federation,” the NFF official told BBC Sport.
“His latest outburst is just unfortunate but the process (to pay him) is still ongoing. There is no attempt to deny Siasia or his assistants their dues.” The Guardian
