Antonis commits to Sydney for another two years
Antonis, previously linked with a move to Parma, is crucial to the Sky Blues' title push this season forming a key partnership in midfield with Serbian Milos Dimitrijevic.
The new deal will see him continue to develop under coach Graham Arnold as he looks to cement his place in the national team.
Antonis, who was due to link up with the Socceroos in Japan last week, was involved in a minor car accident on the way to the airport and withdrawn from the squad.
The 20-year-old has made over 50 appearances for Sydney since his competitive debut in the 2010/11 season.
In career best form after a long injury lay-off, Antonis has developed a taste for the spectacular scoring four times for the Sky Blues, most recently a long range missile against the Central Coast Mariners.
Arnold said he was keen to see the youngster continue his upward trajectory.
“Terry Antonis is an exceptional young talent and I’m pleased to have secured a player of his calibre to Sydney FC for another two years,” Arnold said.
“As the biggest club in the country we need to have the best players and I believe Terry is well on his way to becoming one of Australia’s top midfielders.
“I’m looking forward to working with Terry for a further two years and I hope to see him reach his potential with Sydney FC.”
Having signed on, Antonis said he can now focus solely on the matches ahead.
“I’m thrilled to be extending my time with Sydney FC,” he said.
“I’m glad to be able to concentrate on playing now and I’m keen to develop even further under Arnie and the team.
“Sydney FC are the only Hyundai A-League club for me, they have always been there for me much like a family and it’s a hugely enjoyable place to play football.
“There was never any hesitation when the offer came through and I’m confident I can achieve my goal of winning trophies here.”
