The purchase includes a Luxury Gift Box.

An American Forward in the Dortmund System

Mathis Albert came through the LA Galaxy academy before making the move to Borussia Dortmund, and his inclusion in the club's 2025 FIFA Club World Cup cycle placed him on a global stage that very few players his age have reached. The KidSuper collaboration gives the 2024-25 season a visual identity that is specific and time-stamped, and the Fanshop Match specification means this is the player-spec version, one tier closer to the on-pitch garment than the standard Fanshop Authentic. For collectors in North America who follow American talent in European football, and for collectors in Europe and the Middle East who track the next generation of Bundesliga forwards, this shirt documents a specific moment in Albert's development at the club.

The Fanshop Match Specification

The Fanshop Match shirt is the in-season retail player-spec version that mirrors the on-pitch shirt, often carrying month and year on the inner label as production proof. It is manufactured to the same performance specifications as the shirt worn during competitive fixtures, without being prepared for match use. The KidSuper collaboration adds a further dimension: the 2024-25 Borussia Dortmund KidSuper edition is one of the most visually distinctive shirts in the club's recent history, and the Fanshop Match version is the player-spec retail release of that design, not the standard Fanshop Authentic.

The Shirt in Detail

The 2024-25 Borussia Dortmund KidSuper shirt retains the iconic yellow and black identity of the club while incorporating the creative visual language associated with the KidSuper brand. The shirt bears the number 41, corresponding to Albert's squad number at the club.
