Former Crystal Palace winger John Oster says he has launched a complaint to the Football Association over unpaid wages.
Oster, 30, left Palace at the end of the season in May and is upset he has yet to receive final payments from the club.
"I asked my agent Mel Stein to speak to the FA about it," Oster told Sky Sports News.
"I'm owed four weeks' pay and Palace still owe my agent some money. There's also an issue about money they wrongly took from me about six months ago. I just want it resolved as soon as possible."
Existing squad members also reported not to have received annual bonuses include James Scowcroft, Paul Ifill and Shefki Kuqi.
Palace will make no further comment on the issue after chairman Simon Jordan insisted all members of last season's squad will be paid the outstanding bonus payments that they are owed at the end of July.
He told Palace's official website last week: "The bonus payments are paid annually at my discretion in either June or July and this year they will be paid in July.
"Those members of the playing staff who are staying have been paid in the normal way and those that are leaving will be paid by cheque.
"This method is used for our own administrative reasons and makes good business sense.
"Every player under the chairmanship of Simon Jordan has always been paid and that will always remain the case."
But Oster says he is worried about further payment delays.
He said: "I'm obviously concerned as they say the bonuses will be paid at the end of the month along with my last pay day. I fear the same scenario will arise again.
"If Palace knew they were going to pay us by cheque then why didn't they send the cheques out when we should have been paid last month? I'm not being greedy, I just want what is mine."
