After studying law for six semesters at the University of Zagreb, Soldo's parents convinced him to pursue a career as professional football player.

Runner-up in both Croatian league and cup in his first season back at Zagreb, the next campaign saw Soldo's side complete a domestic double in 1995/96.

After being an exemplary sportsman and role model for younger players all these years, Soldo played his last Bundesliga match for Stuttgart on 6 May 2006.

Soldo was also a long-time member of the national team and made his debut for Croatia in an April 1994 friendly match away against Slovakia, coming on as a 46th-minute substitute for Slavko Ištvanić.
