Mirandes put in an excellent home performance to beat Villarreal 4-2 and eliminate the Yellow Submarine from the cup, with Martin Merquelanz emerging as the star of the show.
The Real Sociedad loanee played a part in all four Mirandes goals, assisting three and scoring one from the penalty spot.
Each assist was different, too, as he helped open the scoring by rising above his marker to flick on a header for Matheus to run through and score with composure. Then, for his second, he sent a teasing cross into the box from a free kick for Odei Onaindia to slide home.
His third was arguably the best of the bunch, though, as he found himself with just the goalkeeper to beat, only to unselfishly square to the right for Antonio Sanchez to pass into the empty net.
Alexander Isak scored two goals of the highest quality against Real Madrid as Real Sociedad eliminated Zinedine Zidane's men.
There was actually (slight) echoes of Zidane's famous Champions League winning goal volley for Isak's first. Although it was nowhere near as good, or as important, as that goal, the Swede did swivel his body into an awkward position to send a left-footed volley into the top left corner, albeit from closer range.
His second was just as good, if not better. After receiving the ball just to the right of goal, he sets himself before rifling a devastating finish into the top right corner this time, with Alphonse Areola barely having time to react in the Madrid goal.
Villarreal may have lost against Mirandes, but Javi Ontiveros can still be relatively pleased with his outing if not the result.
After the hosts had took the lead, it was actually him who got Villarreal back into contention in the first half with a wicked free kick into the bottom corner which seemed to wrongfoot the opposition keeper.
He enjoyed 99 touches in the match, sent six crosses into the box, completed 11 dribbles, and completed 38 passes overall.
Vinicius Junior (7.7) did his best to try and Real Madrid back into the game in the second half versus Sociedad, and set up their second to make it 4-2, but it ultimately wasn't enough.
