Sydney FC has given National Youth League attacker Blake Powell a two-year senior contract.
Powell, 20, has been playing with NSW Premier League side Sutherland Sharks, and was previously a member of Sydney FC's 2011 Asian Champions League squad.
"I'm over the moon. I thought I was coming in just to train but when I was offered a two-year deal I was shocked and I jumped at it," Powell said.
"I put in a lot of extra sessions with the first team when I was in the youth team and I knew in the long run it would be worth it.
"My goal is to try and work my way into the team but I know there's a lot of hard work ahead of me.
"I'm up for the challenge and I'm up for the extra work I know I have to do to get myself into a position where I can play."
Head coach Ian Crook, who coached Powell in the 2011-2012 Sydney FC youth team, said Powell's elevation to the A-League side was well deserved.
"Blake's worked hard for his opportunity and we're delighted to welcome him to the A-League squad," Crook said.
"He spent a lot of time training with the first team while he was in the youth team and I'm sure he'll make the transition well.
"Having coached him in the Sydney FC youth team I know what he is capable of and his style of football suits how we are trying to play.
"He's quick, smart and likes to run at people. I think he'll do well with us if he puts in the hard work and continues to improve."
