Neymar has reportedly warned his Brazilian teammates at Real Madrid about the challenges of playing alongside Kylian Mbappe, describing the experience as 'hell' and 'catastrophic'. Neymar and Mbappe played together at Paris Saint-Germain from 2017 to 2023 but had a strained relationship, often clashing over set-pieces and team dynamics. Journalist Cyril Hanouna revealed that Neymar communicated his concerns to Real Madrid's Brazilians, including Vinicius Junior, Rodrygo, and Eder Militao. Despite these warnings, Mbappe has made a strong start at Real Madrid, scoring four goals in six games. Neymar, who now plays for Al-Hilal, is recovering from a cruciate ligament injury. The tension between the two former teammates casts a shadow over Mbappe's transition to La Liga.
