Brazil's 2026 World Cup preparations under Carlo Ancelotti feature a 26-man squad that includes Neymar despite his Grade 2 calf injury sustained in mid-May, creating uncertainty around his role in the attack for the opener against Morocco. Multiple absences, including Rodrygo's ACL tear and Éder Militão's hamstring surgery, have shifted depth and positional battles, particularly in forward and defensive lines. Recent friendlies and medical updates show Neymar traveling with the team but unlikely to feature immediately, while established starters like Vinicius Junior maintain strong positioning based on club form and prior international appearances. Ancelotti's tactical setup, historical preferences for experienced players, and any late fitness clearances or lineup tweaks ahead of group-stage matches will directly influence whether fringe or recovering players secure starting spots.
