Melbourne Victory young gun Kasey Bos has sealed a transfer to German Bundesliga club Mainz 05, capping off his rapid rise.
Bos, who received his first Socceroos call-up for games against Japan and Saudi Arabia, departs the Victory, who receive an undisclosed transfer fee, to sign with Mainz 05 on a four-year deal through to 2029.
The 21-year-old left-back, younger brother of Socceroos and Westerlo defender Jordy, made just four appearances off the bench for the Victory in 2023-24 but exploded in the most recent A-League Men season.
Bos scored four goals and notched two assists as he made 26 appearances, starting 24, including the Victory's grand final defeat to Melbourne City.
"I've loved every minute I've played at Melbourne Victory," Bos said.
"The club has helped shape my development and build the foundations necessary to take this next step overseas."
Bos's season earned him an Olyroos call-up before his first senior camp under former Victory boss Tony Popovic.
He will now attempt to kick on at Mainz, who finished sixth in the Bundesliga last season.
"For a player to progress from our academy to the A-League team, and now to a top-six Bundesliga club, is a testament to the belief and hard work of many, not least Kasey and his family," Victory football director John Didulica said.
"We are incredibly proud to have been part of his journey so far, and have no doubt he will continue to achieve great things with 1. FSV Mainz 05."
Earlier on Friday, City confirmed talented young striker Max Caputo had signed a three-year contract extension until the end of the 2027-28 campaign.
Defender Callum Talbot meantime departed the champions after three seasons, while Perth have signed former City forward Arion Sulemani on a two-year deal.
