Alaves' squad rebuild under Sergio Fernandez has created opportunities for forwards, especially after losing Joaquin Panichelli and Kike García, and with Asier Villalibre anticipated to depart on loan. Mariano, 31, offers top-flight and international experience at a crucial time for the Basque side, who finished 15th in La Liga last season. Alaves expects Mariano to provide competition and depth, mainly partnering or rotating with Toni Martínez up front. Mariano's physical condition stood out during his trial, addressing prior doubts over his sharpness after a full season without club football.
