What better way to make up for the disappointment of the 3-3 weekend draw than with a colossal away win at one of Europe's most famous arenas? (Albeit a mostly empty one.)
Oscar Cardozo's hilarious ninth-minute sending-off helped Geta immeasurably, but there was little denying the quality of play on offer at times.
First, Ruben de la Red had a shot from the edge of the area deflected past Quim (fnarr) by Edcarlos.
Midway through the second half, Pablo Hernandez hit a trundler from the edge of the box with sufficient accuracy to sneak in at the far post.
Osky was at fault as Benfica pulled one back; he was partially unsighted, but still should have dealt with Pedro Mantorras' long-range effort.
It's a superb result, and it no doubt has many believing that Geta can make it to the next round. Also encouraging was the input of Braulio, who had a fine first half overall, although he faded a bit later on.
Good times, basically.
And here are the highlights:
