The Spanish manager, who guided Bayer Leverkusen to a strong season, declined Marseille's approach after the club parted ways with Roberto De Zerbi. Despite De Zerbi's successful debut season that ended with a second-place Ligue 1 finish, momentum faded this year.
With sporting director Medhi Benatia also having left, Marseille's search for a new coach continues. Among potential replacements are Habib Beye and Sérgio Conceição, with the managerial situation at the French club remaining wide open.
