Serie A side Sassuolo announced on Monday that it had exercised the clause in its loan deal with Marseille to make the signing of Ismaël Koné permanent.
The 23-year-old Canada midfielder has four goals in 20 league appearances this season.
Fabrizio Romano reports the transfer is worth €13 million.
A product of the CF Montreal academy, Koné made his senior debut for the team in early 2022.
After his first Major League Soccer season, Koné made the move to Europe with Championship side Watford following the 2022 FIFA World Cup.
Koné would spend 18 months in England before heading to Ligue 1.
Marseille brought Koné to France in a £15 million move in the summer of 2024.
But the transfer wasn’t a smooth one.
Koné quickly came to loggerheads with manager Roberto De Zerbi, including an infamous bust-up during a training session that was caught by team cameras, and the player was loaned out to Rennes that January after only eight appearances.
With the relationship between player and manager seemingly untenable, Koné joined the promoted Sassuolo on loan.
