Former Socceroos goalkeeper Mark Bosnich has reportedly agreed to a short-term deal with NSW Premier League club Sydney Olympic.

It is believed that Bosnich will be unveiled later this week in what is a major coup for both Olympic and the NSW competition.

After a seven-match stint with Central Coast Mariners last season, Bosnich has resurrected his desire to compete at the top level and is chasing a permanent contract at A-League level or abroad.
