Jose Antonio Camacho has taken his compensation dispute with the Chinese Football Association (CFA) to FIFA following his dismissal as the national team's coach.
Camacho was sacked last month after a disappointing two-year spell in charge that included a record 8-0 defeat to Brazil in September and elimination from World Cup qualifying last year.
The former Spain and Real Madrid boss had 18 months left to run on his reported €2.8 million-a-year contract.
Reports in China said Camacho wants the association to pay his salary for those remaining 18 months, along with his Chinese income tax bill.
On Friday, FIFA confirmed that it had received a claim from the Spaniard, but refused to give any further details while the case was pending.
Reports suggested the claim had been filed by Camacho on Thursday after negotiations with the CFA about his compensation broke down.
The Beijing Times quoted an unidentified CFA official as saying the association would fight the claim and had offered to pay only part of Camacho's remaining salary while refusing to pick up his tax bill.
"We're not quite clear on this matter, but we'll respect whatever Camacho's team decides to do. If he wants to take it to FIFA, then the CFA can only do its best to respond to this suit,'' the official was quoted as saying.
"From the start, we were negotiating in good faith - but the other side did not see it that way.''
