Marseille head coach Roberto De Zerbi has issued a stern warning to Mason Greenwood following his transfer from Manchester United, emphasizing the club's high demands. Greenwood, who faced serious allegations in 2022 that were later dropped, signed a five-year contract with Marseille after a successful loan at Getafe. De Zerbi expressed that he was the first to reach out to Greenwood, reminding him of the club's storied history and urging him to take his new role seriously. However, the signing has sparked significant backlash, including protests from fans and criticism from Marseille's mayor, who decried it as bringing 'shame' to the club. De Zerbi defended his decision, stating he would support Greenwood publicly while holding him accountable privately. He reassured that the club had thoroughly vetted Greenwood before making the signing.
