Super Eagles midfielder, Ogenyi Onazi, is set to take former Serie A club SS Lazio to Federation of International Football Association over unpaid wages.
Onazi spent five seasons at Lazio before joining Turkish top division club Trabzonspor in the summer.
He made 110 appearances for Lazio, scoring seven goals between 2011 and 2016.
“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 on Thursday.
“My agent and lawyer have written to Lazio, but after two months we have heard nothing from the club.”
Onazi added: “We all conclude that the only ideal thing to do is to approach FIFA to enable me get what I worked for.”
Meanwhile, a Lazio official, (names withheld) told BBC Sport that the club would not comment on the matter.
