Madrid will be arriving at the Club World Cup with Carvajal, who's nearing full recovery, and new signing Trent Alexander-Arnold covering the right-back spot. However, the left side of the defence needs bolstering. Currently, Madrid have Mendy and Fran Garcia as options for that area, with Eduardo Camavinga occasionally operating in a makeshift role.
The futures of both Garcia and Mendy are uncertain, even though the latter reportedly signed a renewal last summer. Madrid have already been linked with Huijsen's partner in Milos Kerkez, with club scouts attending Bournemouth's game against Arsenal earlier this month to further evaluate the left-back's potential.
Other names such as Benfica's Alvaro Carreras, AC Milan's Theo Hernandez, and Barcelona-linked Alejandro Grimaldo have also been put forward by the Spanish media.
