Real Madrid B team home-grown midfielder Mario Martin has joined Real Valladolid.

Mario Martín Rielves has left Real Madrid on loan, moving to Real Valladolid until the end of the season. The 20-year-old Spanish midfielder developed in the youth sector of the Blancos, progressing through nearly all categories and eventually reaching the second team and making his debut in the first team. He appeared in 4 matches under Carlo Ancelotti: 1 in the Copa del Rey 2022/23, 1 in 2023/24, and 2 in the last championship.

Real Madrid has loaned 20-year-old midfielder Mario Martin to Valladolid. The 20-year-old, who was little used at Real Madrid, should have more playing time at Valladolid if he can compete with former Hajduk player Stanko Jurić, Cesar de la Hoz, Kike Perez, and Victor Meseguer. Valladolid does not have the right to purchase Martin's contract.

Real Madrid and Real Valladolid have reached a loan agreement for midfielder Mario Martín, who will play for Pucela until June 30, 2025, without a purchase option. Mario Martín, a regular in Castilla under Raúl González Blanco and frequently involved in first-team training sessions by Carlo Ancelotti, made his debut in the Copa del Rey in a Madrid derby against Atlético de Madrid during the 2022-23 season. He also appeared in LaLiga EA Sports last May at Santiago Bernabéu against Alavés. Both clubs confirmed the agreement through brief statements.
