Rayo Vallecano will travel to Granada's Estadio Nuevo Los Carmenes for a Copa del Rey round-of-32 match, rescheduled from December due to Rayo's European commitments. Granada aims to reach the last 16 for the first time since 2021, having progressed past Roda and Tenerife but currently struggling in La Liga with only 21 points from 20 games, placing them in the bottom four. They have historically been tough at home, winning most recent matches at their stadium. Rayo Vallecano, competing in La Liga, the Copa del Rey, and the Conference League, secured a 3-0 victory over Drita in Europe and narrowly advanced past Real Avila in the Copa del Rey. They have an eight-match league winless streak but boast a strong record against Granada, winning nine of their last 11 encounters. Team news indicates Granada's Baila Diallo and Pau Casadesus may be unavailable due to injuries, with goalkeeper Luca Zidane also absent. Rayo faces injuries to Luiz Felipe, Abdul Mumin, Ivan Balliu, and Alemao, with some players like Pathe Ciss away on international duty. Predicted lineups include Granada's Astralaga, Sola, Naasei, and others, while Rayo's probable starters feature Cardenas, Ratiu, Mendy, and others. Despite Rayo's away status, they are favorites to win, with recent form and head-to-head records favoring them. The match is set for January 6, 2026, with a predicted score of Granada 1-2 Rayo Vallecano.
