Barcelona have established one of the world’s best center-back duos this season, with Inigo Martinez emerging as a revelation amid injuries to Ronald Araujo and Andreas Christensen. Martinez's stellar performances have raised doubts about Araujo’s and Christensen’s guaranteed starting roles upon their return. Alongside Pau Cubarsi, who continues to shine as an elite defensive prospect, Martinez has made a strong case as the top central defender this season.

While Barcelona’s defensive depth is impressive, including Jules Kounde as a versatile option, the club remains linked to Bayer Leverkusen star Jonathan Tah. The German international, set to become a free agent next summer, could sign a pre-contract in January. Though Bayern Munich were favorites to land Tah last summer, Barcelona now appear to be leading the race, outpacing Real Madrid, who are desperate to bolster their backline.
