Sydney FC striker John Aloisi admits he's unsure of his future.

The big-money striker comes off contract at the end of the season and has failed to live up to his price-tag

"I’d like to (stay)," the striker tells Australian Football Weekly, "but I haven’t really sat down and spoken to the club yet. I’m just concentrating on the week-to-week and we’ll see what happens at the end of the year."
