Media reports quoted sources close to the Ballon d'Or runner-up as saying that he is expected to be sidelined from three to four weeks. It means he could miss up to seven games in all competitions before the winter break, including against Girona and Athletic Bilbao in La Liga and a Champions League visit to Atalanta.

Vinicius Jr is the latest to join the club's lengthy injury list which includes key players like Rodrygo, Eder Militao, Dani Carvajal, Lucas Vazquez, Aurelien Tchouameni and David Alaba. 

Vallejo, Antonio Ruediger, Ferland Mendy and Fran Gracia are the only players remaining in the Los Blancos senior squad to choose from in defense. Thus, signings are necessary in January to steady a season that is on the verge of collapse.
