16-year-old winger Mathis Albert made a historic senior debut for Borussia Dortmund on Sunday, entering the match against Freiburg during the 88th minute of a 4-0 victory. This milestone makes Albert the youngest American to ever play in the Bundesliga, breaking Gio Reyna's previous record. Albert debuted at just 16 years and 340 days old, following his signing of a professional contract in July 2025.

A native of Greenville, S.C., Albert holds dual citizenship through his parents, allowing him to join Dortmund's youth reserves in 2024. Known for his strong dribbling skills, he primarily plays on the left wing, though his future positioning on the pitch remains to be seen.

Before joining Dortmund, Albert was part of the LA Galaxy youth academy and represented the United States youth teams, earning caps at various levels:

• U-15 in 2023
• U-19 in March 2026 against Wales
• Participated in the U-17 World Cup in 2025

Dortmund now has a promising talent in Albert, who, due to his dual citizenship, may face future decisions regarding national team representation. Similar situations arise with other players like Noahkai Banks, who is navigating his options between the USMNT and Germany.

Albert is now the seventh American to represent Dortmund, joining notable players like Christian Pulisic and Gio Reyna, along with Lennard Maloney, Joe Gyau, Jovan Kirovski, and Cole Campbell. With time on his side, Albert's career trajectory will be closely monitored as he develops in the football world.
