Messi's sons have repeatedly joined him on the pitch during Inter Miami celebrations, most recently after the September 2026 Campeones Cup victory over Cruz Azul, where Thiago, Mateo, and Ciro shared hugs and trophy moments with their father on the field. This pattern of family access following key MLS matches, combined with the Messi family's arrival in Argentina ahead of his October 6 farewell friendly against Benin at Estadio Monumental, supports the 75% implied probability for a "Yes" outcome. The sons train and compete in the club's academy system, positioning them for routine post-match appearances during high-profile events or retirements, while historical precedents of player-family field access in both club and international contexts further align trader consensus with these recurring dynamics.
