After stints in the J-League and the United Arab Emirates, Brosque, 30, is relishing a return to the Sky Blues as new coach Graham Arnold bids to lead the club to its first A-League crown since 2010.
Likely to be unveiled as the club's Australian marquee in the coming days, three-times Skye Blues Players' player of the Year, Brosque remains the club's leading all-time scorer with 30 A-League goals in 104 appearances between 2006 and 2011.
He believes his old club can revive the good times.
"I am close to agreeing something. I am not fully there yet but I am getting there," he said.
"I have been thinking of coming home for a while and when you look at the quality of Shane Smeltz up front and Bernie Ibini as well, Arnie has some quality with Sydney to work with.
"Arnie being there is really an added bonus to any player when you look at his record with Central Coast."
The only matter still to be resolved is rubber stamping Brosque's marquee status, with Sydney having also been heavily linked with Tim Cahill, though it appears more likely the Socceroos talisman will see out remainder of his contract with MSL club New York Red Bulls.
With 13 goals in 56 appearances for Shimizu S-Pulse and 17 in 33 for Al Ain in the UAE's Pro-League, Brosque, who has yet to feature in a Socceroos squad under new Ange Postecoglou, was a regular under previous coach Holger Osieck - before suffering an abdominal injury a year ago.
On his looming return to Allianz Stadium, the former fans' favourite said: "It's hopefully going to be another chapter and a good one.
"If everything works out then it would be great to help the team make a big impact next season.
"It's all a part of trying to bring a title to the Sydney for any player who goes there.
"I had some great times at the club and those memories never fade."
Brosque, who parted company with Al Ain in May, is likely to be used as a wide attacking player by Arnold.
