The Frozen Moment
The 2026 World Cup in North America. Belgium, the Red Devils, had assembled a squad blending experience with exciting young talent. For Joaquin Seys, the 21-year-old left-back from Ostend, his tournament involvement was brief but significant.
Seys was named in Belgium’s World Cup squad and made a single appearance, playing 30 minutes as a substitute in the quarter-final defeat to Spain.
