Luka Dončić (age 11.9 years) was interviewed by Slovenian TV station POP TV during the Olimpija - Barcelona Euroleague matchup in Ljubljana. Luka was at that time a "mop boy" during Euroleague games. The TV station introduced him a little bit, as well as reported on the game. This was probably Luka's first TV interview (watch it here).
