Hercules' on-loan midfielder Royston Drenthe is threatening to quit the club and return to Real Madrid unless his unpaid wages are met.
The Alicante club have admitted they owe players' wages for November and December and claim they will be able to pay salaries in mid-January when they receive expected income.
Drenthe claims he has only been paid for one month of the six months he has been at the club and insists he can no longer work without being paid.
The 23-year-old joined Real Madrid in August 2007 from Feyenoord, but was unable to secure regular first-team football having made only eight Liga appearances for the club last season.
"If they don't find a solution for my pay I will go back to Real Madrid to train and regain my strength," Drenthe told Marca.
"Of the six months I have been here they have only paid me for one, and they owe me five. I have a lot of expenses and I cannot work without pay.
"At Hercules they have given me a lot of talk but no action. Until there is action, I am not going back. I love the Hercules fans but this is not right."
