It's understood the Japanese playmaker and Wanderers marquee will announce the contract extension on Monday.

Ono, 33, has been one of the stars of the Wanderers who have exceeded all expectations this season heading into the season blockbuster with Central Coast on Saturday.

His attitude and all-round play has been vital to the team's success as they eye a potential top spot in the A-League in the club's first season in existence.

The Wanderers' many fans have taken to the Japanese great - nicknamed 'genius' in Japan for his silky skills and vision - and the feeling has been mutual.

Ono's goals have been spectacular and his link up play with the likes of Youssouf Hersi has been eye-catching this season.

Ono is now the second big overseas marquee to commit to the A-League after last week's announcement that Alessandro Del Piero is back for at least another season with Sydney FC.
