Nigeria international Ogenyi Onazi has asked Fifa to intervene in a dispute with his former club Lazio who he says owe him two months' salary.
The 23-year-old left Lazio for Turkish side Trabzonspor in August.
"We have no option but to go to Fifa to ask the disciplinary committee to act on Lazio's refusal to pay me," Onazi told BBC Sport.
"My agent and lawyer have written to Lazio, but after two months we have heard nothing from the club."
Onazi, who spent five years at Lazio and scored seven goals in 110 appearances, added: "We all conclude that the only ideal thing to do is to approach Fifa to enable me get what I worked for."
A Lazio official, who declined to be named, told BBC Sport that the club would not comment on the matter.
