The Duvnjak family is a handball family. Mother Ivanka played handball, so did father Ivan, who later became a successful coach. Domagoj started his handball career at Đakovo, where he was also born on 1 June 1988. He grew up on the handball court next to his family. At the age of 16 he played for his own Đakovo in the Croatian Premier League. He was the top league scorer playing in the jersey of his hometown club. His goals kept Đakovo among the best. Naturally, something like that could not have gone unnoticed. He was first called to the Croatian youth national team, then to the junior national team and finally to the senior national team. Of course, it was not to be expected that he would remain in Đakovo. A transfer to the most powerful Croatian club Zagreb was virtually inevitable.
