FC Basel sign two new players: Louis and Harder boost squad

FC Basel kick off season with two new signings

FC Basel have announced two new signings on Tuesday: Coleen Louis and Jonas Harder will bolster the squad for the new season. The 21-year-old left-back arrives from Amiens SC, while the 20-year-old midfielder joins from ACF Fiorentina. Both have signed four-year deals with the Swiss club. The Super League season kicks off on July 19, 2026, and Basel currently sit fourth in the standings with zero points - but the new arrivals aim to change that.

Who are the new signings?

Coleen Louis, 21, joins from Amiens SC in France’s third tier after the club’s relegation from Ligue 2 in the 2025/26 season. The French-Guadeloupean dual citizen brings experience from northern France and is expected to shore up Basel’s defense. His contract runs until summer 2030.

Jonas Harder, 20, arrives from ACF Fiorentina. The midfielder came through Fiorentina’s youth system and spent last season on loan at Serie B side Calcio Padova. He started as a regular before injuries derailed his campaign. Harder has also signed until 2030. Both players inject fresh energy into a Basel side that struggled in pre-season friendlies.

Why these transfers matter for FC Basel

The two signings address key gaps. Louis replaces a defensively shaky full-back, while Harder adds energy to midfield. Basel currently sit fourth in the table - but the Super League hasn’t even started yet. The new arrivals must adapt quickly to help the club meet its ambitious targets. Head coach Fabio Celestini is banking on young talent with upside.

The four-year contracts signal Basel’s long-term vision. The signings are part of a broader strategy to return the club to the top of Swiss football. Fans are hoping for a strong 2026/27 season - and the new faces could be the difference.

What’s next for the new signings?

Louis and Harder now face the challenge of integrating into matchday squads. Pre-season training is underway, but competition is fierce. Neither player has Super League experience - a quick start is vital. Basel still has time to fine-tune details before the season opener.

Fans will get their first look soon: the Super League season kicks off on July 19, 2026. Until then, one question remains: how quickly can the new signings find their rhythm? The clock is ticking - and expectations are high.
