Sources in Japan have confirmed that Shimizu S-Pulse have released Ono to Western Sydney Wanderers  and his arrival is now imminent.

The attacking midfielder - known as 'Genius' as a youth player - is an attacking midfielder who played 56 times for country and had spells in Europe with Feyenoord in the Eredivisie and Bundesliga's Vfl Bochum.

He returned to Japan to join Shimizu S-Pulse in 2010 for family reasons in a reported €300,000 transfer deal and has since played more than 60 games for the club, scoring eight goals.

The signing is expected to be confirmed tomorrow, bringing an end to an epic last minute hunt for a big name signing for the new side after Sydney FC snared Alessandro Del Piero last month.

The FFA-financed club opened negotiations with German legend Michael Ballack who is currently available on a free transfer,

But talks are understood to have broken down over covering the cost of Ballack's tax bill in Australia.

The German is understood to have wanted a salary of $1.6million after tax, which put the cost beyond the club's budget.

Ballack's representatives had hoped to force a deal through before the start of the season, but negotiations with Ono progressed rapidly after Ballack's demands became known.

Ono is expected to join his new club next week, just days before the season kicks off on Friday night.
