Former Nigeria U-23s head coach Samson Siasia has reportedly handed the Nigeria Football Federation a two-week ultimatum to pay his entitlements or face embarrassment.
The NFF are yet to offset Siasia's five months' salary arrears from the start of April to August 2016 despite promising to pay him recently.
And the former Super Eagles forward is running out of patience with the governing body.
"I have given them a two-week ultimatum to pay me or I will sit inside the NFF office in Abuja until I get paid," Siasia told BBC Sporton Saturday.
"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."
Siasia recently led the country's Olympic team to a bronze medal finish at Rio 2016.
