Young gun Stefan Colakovski has swapped Melbourne City for Perth Glory, while the A-League Men grand finalists have parted ways with former Premier League defender Carl Jenkinson.
Colakovski, 22, has joined the Glory on a two-year deal after spending seven years at City, coming up through their academy.
The forward won two premierships and played a crucial role in the breakthrough 2020-21 championship at City.
But Colakovski fell out of favour last season with Jamie Maclaren, Mathew Leckie, Andrew Nabbout and Marco Tilio ahead of him.
“We welcome Stefan to what is the start of a rebuild here,” Glory head of recruitment Andy Keogh said.
“He’s a fantastic young talent who fits a key strategy of the club in developing young Australian players for the future.
“Stefan will bring a winning mentality to our club having previously been part of a fantastic club in Melbourne City.”
Former Arsenal and West Ham defender Jenkinson’s six-month loan stint from Nottingham Forest, which started in January, has ended while City also released Tsubasa Endoh and Anthony Lesiotis.
Central Coast midfielder and Olyroo Josh Nisbet has re-signed with the Mariners for two seasons.
Meanwhile Adelaide have parted ways with former captain Michael Jakobsen.
The 36-year-old accumulated 95 appearances over four seasons, including winning two Australia Cups, in 2018 and 2019.
