Manager Marcelino will leave Villarreal at the end of the season.
The 60-year-old has secured Champions League football for a second straight year with Villarreal currently in third place in La Liga.
Confirming his imminent departure, the Spanish club said: "Thank you from the bottom of our hearts, Marce, for everything you have given to this club and its fans.
"We wish you all the best in your future sporting endeavours."
The former Marseille and Sevilla manager began his second spell with Villarreal in 2023 and guided them to a fifth-placed finish last season.
Marcelino was reportedly only offered a one-year extension to his contract in January.
Villarreal were eliminated at the league phase of the Champions League, losing eight of their nine games, but have impressed in the league once more.
