The 18-year-old has worn the Black and Red shirt since 2013 and he has made 16 appearances for the Bayer 04 U19s in the  current U19 Bundesliga West campaign. He has also been very much in demand with the Germany youth teams. Boller (pictured above in the middle with Lucas Alario and Sam Schreck in the game at Heidenheim) has earned 15 caps for the Germany U17  team and he was a first choice in central defence  at the 2017 European Championships in Croatia as well as the World Cup in the same year in India. He  played alongside Kai Havertz  in the Bayer 04 U17s in 2016 when they won the Germany U17  championships with a 2-0 victory over Borussia Dortmund in the final.
