Jeltsch beat Cologne youngster Saïd El Mala and Hoffenheim's Max Moerstedt to the annual prize recognising Germany's brightest football talents. He is the first Stuttgart player to win the U19 Fritz Walter gold medal.
The central defender joined Stuttgart in January 2025 after impressing for Nuremberg in Bundesliga 2 as well as for Germany at youth international level, where he is a former U17 European and world champion.
He has since made 19 appearances for the Swabians in all competitions, coming on against Arminia Bielefeld in the DFB Cup final last year as Stuttgart won the trophy.
