Sydney FC have signed Melbourne City and Socceroos defender Alex Wilkinson.

Wilkinson has signed a two-year deal with the Sky Blues, after playing 10 games since signing with City in January.

“It feels great to be coming back to Sydney and playing for the club that represents my home city,” Wilkinson said.

“Sydney FC is a huge club and I have no doubt we will be challenging for the title next season.

“There are a core group of very good players at the club and next season I believe we will be more than capable of winning silverware.

“It's going to be a great challenge for me and I can't wait to link up with the squad.”

Wilkinson, who is a two-time A-League premiership winner, links up with former coach Graham Arnold.

“Alex has great experience in all forms of football and brings with him a wealth of knowledge of the game having played in Australia as well as overseas and at international level,” Arnold said.

“He was outstanding in the Socceroos World Cup campaign in Brazil and in the Asian Cup winning side last year and has an exceptional work ethic and leadership qualities.

“He will bring added stability to our back line and will help improve the game of our younger boys and those around him.”

The 31-year-old has 16 caps for Australia.
