The quick goal came despite Eibar coach Jose Luis Mendilibar's decision to line up only one striker and three midfielders, apparently to avoid the defensive errors that had proved costly in recent matches.
VAR stepped in once again in the 22nd minute, when a penalty call by referee Iglesias Villanueva was overturned as it apparently showed that the foul committed by Alaves defender Ruben Duarte was outside the box, but the Spanish player was sent off for preventing a promising attacking chance.
Outnumbered, Alaves brought on right back Carlos Vigaray to replace Spanish striker Borja Baston, and managed to keep their 1-0 lead when the first half ended.
Apparently seizing the game's momentum, Eibar managed to pull off the win in the first minute of stoppage time thanks to Diop's close-range header.
