Former Central Coast Mariners marquee Patrick Zwaanswijk is taking legal action against the A-League club for wrongful dismissal.

Former Dutch first division player Zwaanswijk had a three-year contract with the Mariners until his retirement in May 2013, when he was re-employed as head of youth and community football.

The Mariners are accused of terminating his position in June, 13 months into a three-year contract.

Zwaanswijk's lawyer Peter Moore said his client is now seeking almost $250,000 in lost earnings, as well as damages for breach of contract and loss of reputation.

"He is now not in receipt of the remuneration that was promised, which included superannuation, car, laptop computer and other benefits," he said.

"He had settled himself in on the basis that he didn't need to find any other employment because he had this position pursuant to the contract for three years.

"One year into the contract the club makes this decision by itself and he then has to find other employment, that's what he's looking for at this point in time."

Mr Moore says negotiations between the two parties have broken down and if the matter cannot be resolved, it will go to court.

The former defender played a crucial role in the club's grand final victory in 2012-13, scoring the opening goal in the 2-0 win over the Western Sydney Wanderers.

Zwaanswijk argues he has suffered loss, and continues to suffer loss and damage.

The statement of claim was lodged with Gosford District Court late last week.

The ABC has contacted the Mariners but has been told the chief executive is currently unable to comment.
