Bosnich, 37, was unveiled today with club officials excited at the opportunity that the signing brings in exposing the club to a new fan-base.

Club general Manager Nick Kambounias said the club was taking a keen interest in the B-League concept.

"We are already structuring the club with interest from investors to make a serious application," he said at today's launch.

A task force has been started to investigate how a B-League would be structured. It's early days but the club is looking to position itself as a viable club for such a competition.

"The signing of Mark Bosnich is another example of how serious we are."

He added that the signing of Bosnich should only be viewed as a stepping stone back into the A-League or even Europe.

Bosnich is set to make his debut this Sunday at Belmore Oval against Bonnyrigg White Eagles (4pm kick-off).

The club is expecting a ten-fold increase in its usual attendance with a crowd of around 3,000 tipped.

Olympic coach Nick Theodorakopoulos hailed the signing as one of the biggest events in the club's history. He described the former Manchester United star as "larger than life".

Bosnich is also set to play in a number of high-profile friendlies for the club. Olympic will assist the Jets prepare for their ACL knockout round clash with Pohang Steelers by playing a friendly against the A-League side on June 16.

And the July friendly with Sydney FC is close to being signed off with a July 18 or 19 date likely.

"I have been keeping in relatively good shape, as you can all see," said Bosnich with a smile.

"I've got a reinvigoration for life. Hopefully the body will hold up and I'm confident it will. I'm in good hands. The adventure continues."

And Bosnich made an impassioned plea for a B-League to unite the game's traditional supporters with the "new football" of the A-League.

"The fact that we took soccer away from its ethnic roots and so forth was the right thing to do at the time.

"But we shouldn't forget our pioneering roots. And in Sydney Olympic we have one of the founding clubs," he said of the one-time NSL champions and a club that's produced players such as Nick Carle, Brett Emerton and Shannon Cole.

"I believe Sydney Olympic would be at the forefront of a B-League and I think by doing this [signing for Olympic] will greatly enhance the opportunity of the B-League being something that has to be done.

"But I also want to be respectful to Sydney Olympic because without them I wouldn't have this springboard."
