Joaquin Seys is at left-back in Total Football Analysis’ 2025 Breakout XI.
It’s been quite the year for Seys, who has gone from playing in Club Brugge’s reserve team, Club NXT in the second tier, to becoming a nailed-on starter for the senior squad in a matter of months.
What catches the eye about him is his conversion to right-back since joining Nicky Hayen’s team in the summer, having never played the position before at Club NXT and indeed performing as well as he has since switching flanks.
He also earned a call-up from Domenico Tedesco for the Belgian senior national team for November’s UEFA Nations League games.
However, he couldn’t participate after picking up an injury shortly after the announcement.
And to put the cherry on top of the cake, he recently won the Dominique D’Onofrio Prize, awarded to the best debutant of the year in the Belgian Pro League, which made him only the second Club Brugge player to win the award after Charles De Ketelaere.
Quite an impressive progression in a short space of time for a player who had never represented his country beyond the U19s at the national level, and the way things are going, there’s a lot more in store for Seys in 2025 and beyond.
We may be cheating a bit by including him as a left-back, given that he’s been a mainstay on the opposite side of his club in recent months.
But given that he’s still naturally a left-footed left-back and that he is one of the fastest-rising young players in Europe in either position, we believe his place in our team is more than justified.
This scout report and player analysis will examine Seys’ progression this season, his strengths and areas for improvement, and what makes him one to watch in 2025.
