Okon's contract with the Gosford club expires at the end of the season, with Sunday's 5-2 loss to Melbourne Victory marking his 50th game in charge.

The former Socceroo has only won 10 games as Mariners coach, with the club finishing last term in eighth with 23 points and currently sitting second last with four games to play.

Central Coast are already practically out of finals contention, with a 10-point buffer behind sixth-placed Western Sydney.

The Mariners appeared to have made strides forward early in the campaign, particularly after a 2-0 win over champions Sydney FC, but have faded.

Central Coast endured an 11-game winless run and have only managed one win in their past 14 matches.

"I don't know," Okon said, when asked if results or performances in the final four rounds would decide his future.

"I'm not even thinking about that to be honest.

"We finish the season and then, no doubt, we'll know more. But it's not on my mind."

The Mariners, who have won two premierships and one championship, haven't qualified for the A-League finals since the 2013/14 season.
