Although the 18-year-old was born in Slovenia, he comes from Bosnian parentage and he has made up his mind who he wants to play for.
Vuckic: "I made my mind up some time ago and I will not change it.
"I'm not hiding it. I'm proud of my roots, but I'm also proud of being Slovenian.
"Slovenia is my country. I was born there, I made my first steps there and I have friends there.
"It would be very hard to say no to Slovenia, but it is always nice that someone else wants you.
"But I don't care about the rumours. I've know for a while who I want to play for - Slovenia!"
