A late equaliser from Cultural’s Julen Castaneda cancelled out Angel Correa’s opener for Atletico before the extra period saw dramatic scenes when Sergio Benito volleyed the winner.

Vitolo missed the best opening of the first period for the away side, poking wide from Joao Felix’s through ball.

But Correa made no mistake just past the hour mark when he latched onto the Portugal forward’s flick to put Atletico ahead.

The visitors pressed for a second and Cultural were indebted to goalkeeper Lucas Giffard for keeping them in the game with a string of fine saves before Castaneda smashed home an equaliser six minutes from time to send the game into extratime.

The Reino de Leon stadium was then sent into delirium as Benito volleyed the ball in at the far post after 108 minutes to ensure the Segunda B outfit of a place in Friday’s draw.
