Žiga Daneu has been part of Cedevita Olimpija’s structure since early youth. His grandfather is the legendary Ivo Daneu, and his father is Jaka Daneu, both of whom, in their own way, left a significant mark on the Ljubljana club and Slovenian basketball. In between, Žiga honed his skills at Ljubljana’s Ilirija and Domžale’s Kansai Helios, and before the start of the 2024/25 competitive season, he returned to the Ljubljana club, where he earned opportunities in both the BKT EuroCup and the AdmiralBet ABA League, while also becoming the MVP of the Slovenian Super Cup.

In the 2024/25 season, Žiga Daneu played in 19 regional league games and nine European Cup matches. In the latter, he averaged just under nine minutes on the court, scoring 1.4 points and grabbing 1.1 rebounds per game, while in the regional league, he averaged 1.0 point and 1.2 rebounds per game in 6.6 minutes of play. At the Slovenian Super Cup in Laško last September, with perfect shooting from the field (5/5 for two, 2/2 for three), he scored 16 points and collected three rebounds.

Žiga also successfully wore the Dragons’ jersey in the national championship playoffs, where he received more playing opportunities – in the quarterfinals against GGD Šenčur, he averaged 11.5 points and 6.0 rebounds per game, in the semifinals against Podčetrtek, he averaged 6.0 points, and in the finals against Krka, he averaged 2.5 points per game. In the 2024/25 season, Žiga won all three national titles with the Ljubljana club.

With his strong performances, Žiga earned an invitation to the Slovenian senior men’s national team, for which he played in four official matches during the EuroBasket 2025 qualifiers.
