AaB Aalborg cruised through to a UEFA Cup last-16 showdown with Manchester City after blitzing Deportivo La Coruna with three goals in four first-half minutes to secure a convincing 6-1 aggregate win.
Trailing 3-0 from the first leg, Depor needed to produce another of their European comebacks to have a chance of progressing and when Sergio's deflected shot put them ahead in the 38th minute the miracle looked on.
However, within seven minutes of that strike the tie had been well and truly settled as AaB netted quickfire goals through Luton Shelton, Andres Johansson and Thomas Enevoldsen.
Pablo Alvarez's late red card added to the hosts' misery.
Depor have claimed unlikely comeback successes over the likes of AC Milan, Paris St Germain and Brann Bergen down the years, but they could not repeat the feat tonight and might have been put out of their misery a lot earlier than they were.
With just 10 minutes on the clock at the Riazor, AaB forward Shelton looked certain to score as he raced onto a through-ball and skipped past the outrushing Depor goalkeeper Daniel Aranzubia, but Diego Colotto managed to get back to make a crucial last-ditch block.
Depor then enjoyed a promising half-hour spell that saw Omar Bravo threaten twice, including having a goal ruled out for a marginal offside, while Filipe and Angel Lafita also went close.
The Spanish side then got the goal they so desperately needed when Sergio's 25-yard shot took a slight deflection that the wrong-footed AaB goalkeeper Karim Zaza was unable to keep out.
Depor's joy was short-lived though as AaB hit back in devastating fashion with three goals just before half-time.
Andres Due, who netted a brace in the first meeting, created the first two from set-pieces, with Shelton and then Johansson both heading home from close range following flick-ons.
AaB then put the tie beyond any doubt with a third goal 60 seconds later, Enevoldsen volleying into an unguarded net after Shelton's low shot had been parried by Aranzubia.
Depor continued to push men forward in the second half in a bid to salvage some pride but AaB soaked up the pressure without too many problems.
To compound the home side's woes they lost Alvarez to a late sending-off after he was shown a second yellow card for a foul on Due.
