The 20 year-old Bosnian spent three years on Liverpool's books, but never played for the Reds due to work permit difficulties.
"I was young when I went there, I had just turned 16 years old," he recalled to Jutarnji List.
"But, it's not the reason it did not work out. I could not get a work permit.
"However, I returned a better player than I was, it was a great experience, which helped me a lot.
"I'm not sorry at all."
