I’m not even convinced he plays for them next season. He’s still very young. They also have a 2007 born winger that they are starting to integrate into their reserve team that’ll probably get a shot before Mathis. The way things are going Mathis will get there, but it might be the 2026-27 season.
Five American Prospects Breaking Through in German Football Mathis Albert (2009) At just 15 years old, Albert has already played over 700 minutes for Borussia Dortmund’s under-19 squad, including starts against FC Barcelona and Real Madrid in the UEFA Youth League. Only Yousouffa Moukoko made his debut for Borussia Dortmund’s under 19 squad at a younger age, while Albert is also amongst the five youngest players to feature in the UEFA Youth League this campaign. And what is most remarkable is that Albert is not an unprecedented physical phenomenon like Moukoko was during his academy years. Rather, he is thriving against opponents almost 4 years older off the merit of his pure technical mastery and game intelligence. Albert's dribbling is a masterclass in precision and poise. His tight touches and upright posture allow him to glide through defensive lines, adjusting seamlessly to the movements of his opponents. Whether operating on the left or right flank, the U.S. youth international exhibits a natural tendency to drift into central areas, combining sharply with teammates or carving out shooting opportunities for himself. What truly makes Albert special is his ability to translate his flair into end product—something that sets him apart even among his gifted peers. In just 472 minutes of U19 Bundesliga action, Albert has notched five goals and an assist, including a stunning curling effort in his first derby against Schalke 04 (below).
