Deportivo Alavés striker Mariano Díaz will be available for Tuesday's La Liga clash against Real Madrid at the Santiago Bernabéu.
The 32-year-old forward returns to the Bernabéu for the first time since June 2023, when he was still a Real Madrid player.
Mariano has not scored in La Liga for four years.
The update was reported by MARCA on Monday ahead of the Matchday 33 fixture on 21 April 2026.
Mariano joined Alavés on a free transfer in August 2025 and has featured in 10 La Liga matches this season without finding the net.
Alavés, currently battling near the bottom of the table, travel to the Spanish capital with Mariano in the squad as they face second-placed Real Madrid.
The former Real Madrid academy graduate will line up against his old club in what is expected to be an emotional evening at the Bernabéu.
All attention is now on tomorrow's match, with kick-off scheduled for 21:30 local time.
