Atlético Madrid are ten-times Copa del Rey winners, famously beating Real Madrid at the Bernabéu in the 2013 final in, what was, Diego Simeone’s first full-season at the helm.
More recently, los Colchoneros have suffered two embarrassing early exits in this competition, ousted by Cultural y Deportiva Leonesa in 2020 and Cornellà 12 months later.
Given that Atleti are out of European competition, finishing bottom of their Champions League group, the Copa should be a priority for Simeone’s side.
Arenteiro will believe they can add their name to that list of Atleti giant-killers.
The Segunda Federación (fourth-tier) outfit have reached the second round for just the second time, running Valencia close 12 month ago, eventually beaten in extra time.
This year, Arenteiro have already beaten a La Liga outfit, ousting Almería, thanks to goals from Antón Escobar and then Rafa Mella.
So, will Atleti’s generally miserable season get even worse at Estadio Municipal de Espiñedo?
