Greek Australian rising star Kosta Antonopoulos has officially signed with La Liga club Rayo Vallecano, joining the club’s Juvenil A Squad ahead of the 2024/25 season.
The exciting forward, hailing from Melbourne, continues to make waves in European football after catching the eye of scouts during a recent showcase by Anthem Sports.

Antonopoulos, known for his technical ability, sharp finishing, and football intelligence, becomes one of the few Greek Australian players to enter the top-tier youth system of a Spanish La Liga club.
His move to Rayo Vallecano represents a major milestone in his professional journey and highlights the increasing footprint of Australian talent on the European stage.


This landmark deal was facilitated by renowned FIFA-licensed agent Morris Pagniello, who continues to lead a number of successful international transfers through his global football network and player development initiatives.
“I’m incredibly proud of this next step in my career,” said Antonopoulos.
“To be part of a club with such tradition and a pathway to top-level football is a dream come true. I want to thank everyone who believed in me — especially my family, coaches, and my agent, Morris Pagniello.”
