Union Saint-Gilloise Sign 22-Year-Old Mateo Biondic From Fourth-Tier Eintracht Trier

The reported bonus-linked fee would be Eintracht Trier’s biggest sale since the mid-1990s.

Overview

Eintracht Trier confirmed the move and publicly thanked Biondic following the announcement.
Local reporting says the fee can exceed €200,000 with bonuses, marking a rare windfall for the Regionalliga Südwest club.
Biondic logged 20 goals and 14 assists in 68 appearances for Trier after being made permanent in summer 2025 on a contract through 2027.
Higher-tier German sides including Holstein Kiel, SC Paderborn and 1. FC Nürnberg had recently scouted the 1.90-meter forward.
He could feature in the Champions League knockout phase only if Union advance from the league phase, where they are currently one point off the cut with Bayern Munich and Atalanta still to play.
