Felice Mazzù sees his Pro League prodigy called up in Switzerland

Roggerio Nyakossi, central defender of Louvain, received his first call‑up with the Swiss national team after injuries forced Granit Xhaka (Sunderland) and Miro Muheim (Hamburg) to withdraw, thus offering the young Swiss a great recognition.

One man’s misfortune is another’s fortune, injuries in Switzerland opening the door for Nyakossi.

Nyakossi is among the Jupiler Pro League players who play outside the big Belgian clubs but attract the attention of clubs from the five major European leagues.

In January 2025, the 22‑year‑old Swiss left Olympique de Marseille’s reserve team to join Louvain for €800 000.

Career and market value

At Den Dreef, he quickly established himself as an indispensable part of the team.

Last season, Felice Mazzù regularly praised his qualities, both in duels and in ball recovery.

According to Transfermarkt, his market value has risen to €5 million, an estimate that could still increase in the coming weeks.

Nyakossi, former captain of the Swiss U21 side, could make his debut against Slovenia and Scotland in League B.

Switzerland leads its group by five points, almost certain of promotion to League A.
