In February 2010, following the club's 2009–10 season, McKinna chose to move into a new role, becoming Central Coast's Football and Commercial Operations Manager. Socceroos assistant manager Graham Arnold was appointed as the club's new manager, becoming its second manager. In the lead-up to the 2010–11 season, numerous transfers resulted in changes to the club's squad. The Mariners announced the signing of 2005 Under 20s World Cup winner Patricio Pérez of Argentina in June 2010, followed by Dutch defender Patrick Zwaanswijk. In July 2010, it was announced that the Mariners' women's team would not compete in the 2010–11 W-League competition. The club stated that financial reasons were behind the decision, after Football NSW withdrew its funding.
