The Australia international wants to enter coaching, but not just yet as he chases a championship winner's medal with his Georgian club this season.
"I still don't know what I want to do after this season," Zelic told tribalfootball.com. "My career has been so unpredictable that it's impossible for me to plan, I'll make that decision closer to the time.
Zelic admits he still has plenty of games left in his legs.
"It's all about playing. Playing is still as much fun for me as it was when I started. I can't believe I'm 36 and nearing the end of my career as a professional footballer, I still feel like a kid kicking a ball around in the backyard, the enthusiasm and love for the game is in the blood and always will be.
"Yes, I plan to eventually to get a coaching license when I finish playing but I'm not interested in coaching a club immediately.
"I love and miss Australia heaps and want to spend a lot of time there developing junior footballers, helping them with their game and later career paths - basically passing on my knowledge and also what I've learnt from working with some of the best coaches in the world to our kids in Australia.
"I want to help them improve as players and eventually benefit by making a career out of football, this is definitely something that interests me."
