Western Sydney's marquee man could be heading for the exit door with the former Japanese international still waiting for a new deal
Ono is out of contract at the end of the season after joining the Wanderers as a marquee player in 2012.
The 34-year-old has expressed his desire to see out his career in Sydney's west, while team-mate Youssouf Hersi, who is also out of contract, wants to remain at the club beyond 2014.
But coach Tony Popovic is in no rush to offer the pair new contracts, despite handing striker Labinot Haliti a two-year extension.
Ono's contract situation has alerted a host of rival A-League clubs, and the former Japanese international was giving nothing away at the competition's 'Summer of Football' launch in Sydney.
"I don't want to comment about this question actually," Ono told reporters on Wednesday.
"But if you're a football player if you know some club offer to me is good I'm very happy.
"But I say I love to stay with Wanderers."
While Ono's future remains clouded, his form since arriving in Australia has sparked interest in the A-League, with former Japan team-mate Naohiro Takahara considering a move Down Under.
The 34-year-old enjoyed a return to form with Tokyo Verdy in Japan's second tier, scoring 11 goals for the season.
However, Ono claims Takahara is unaware of reports linking him to the A-League.
"I had contact with Taka two days ago and he didn't know about any news from here, it was a surprise for him," he said.
"If he comes for sure, I'd like to see him here".
