Central Coast have signed former A-League championship winner Michael McGlinchey for the next two seasons.
The New Zealand international, who won the title with the Mariners in 2013, has spent the last four years with Wellington Phoenix.
The 31-year-old said it was a "no brainer" to return to Gosford after receiving a call from new coach Mike Mulvey.
"They didn't need to sell me the club, I know what the club is all about and I wanted to come back and play for the Mariners," McGlinchey said.
"When I was here I was so happy on and off the pitch - we went on to be really successful, I've got some very fond memories from my time here and I want to create some more."
McGlinchey joins Corey Gameiro, Matt Simon, Jack Clisby and Jonathan Aspropotamitis as new additions at the Mariners.
Mulvey, who steered Brisbane Roar to the A-League double in 2013-14, is seeking to return last season's wooden spooners to their former glory.
