Jonathan Calleri scored a hat-trick as Espanyol ruined Wolves’ unbeaten away record in the Europa League with a 3-2 victory, but it could not stop the visitors progressing to the last 16, 6-3 on aggregate
The forward's 91st-minute header handed the Spaniards victory as they gained an element of revenge on Wolves after a thumping 4-0 defeat at Molineux last week
Matt Doherty's 79th-minute equaliser looked to have earned Wolves a hard-fought draw, although Pedro Neto squandered a glorious chance to win it as he shot wide when faced with an open goal in the closing stages
Calleri also scored on 16 minutes and from the penalty spot 12 minutes after the break, either side of Adama Traore's equaliser in his hometown
Wolves now turn their attention to Friday lunchtime's last-16 draw, while Espanyol will focus on their La Liga relegation battle
Espanyol came out with more determination than they had at Molineux last week and moments after Calleri was flagged offside after testing Rui Patricio, he opened the scoring
Sloppy defending down Wolves' right saw Adria Pedrosa get to the byline and his ball across the six-yard box was met by Calleri, who fired it into the roof of the net
That lead was short-lived, however, and it was Traore, raised just down the road from the RCDE Stadium but a former member of city rivals' Barcelona's academy, who got the equaliser
 Daniel Podence picked out his team-mate in the box and, after his first effort was blocked, he made no mistake with his second bite at the cherry, finishing into the bottom corner
There was little in the way of goalmouth action aside from the goals in a first half played like a pre-season friendly, but it livened up after the break as Espanyol made more of a fist of it
Wolves' brightest spark, Podence, had the first opportunity of the second half as he fired over from 25 yards out, before Max Kilman was penalised as his high foot caught David Lopez in the box after his defensive colleagues failed to clear
 Calleri made no mistake from the spot, sending Patricio the wrong way
Morgan Gibbs-White had Wolves' best chance prior to the equaliser, firing over after Doherty played him in behind and he had shrugged off the attentions of Espanyol defender Naldo
Doherty got himself on the scoresheet 15 minutes later, although the goal was all about Kilman and Podence's intuitive thinking
 The former took a quick thrown-in as Podence stood five yards behind the home defence
 He picked the ball up, raced into the box and passed the ball across the six-yard box for Doherty, who simply could not miss
Wolves should have won it eight minutes later through Neto
 A poor backpass allowed the substitute to steal in ahead of 'keeper Andres Prieto
 Faced with an open goal but under pressure from a defender, Neto shanked an effort wide from 18 yards with only an empty net in front of him
His anguish at that miss only deepened in the first minute of stoppage-time as Calleri was alert in the box to nod the ball beyond Patricio, completing his hat-trick and ending Wolves' impressive away run in the process
Nuno Espirito Santo was clearly frustrated with his side's display at the final whistle, but they remain among the favourites to win this competition and will be one of the sides teams want to avoid in two weeks' time
Nuno admitted he was powerless to stop rising expectation levels after his side reached the last 16
He said: "It's impossible, my job is this squad
 How can I manage outside expectations?"We are on the journey, we focus on our daily process, tomorrow we will train, Saturday we're going to train and then we will travel to play Tottenham [on Sunday]
"It's massive for the club and city, we are happy
 We want to keep going
 This gel between players is amazing
"We should have done better [in the second leg] but the hard work was there and we made something which is massive for us
 It was a lot of hard work last season so we are proud of what we have been doing
"Wolves continue their quest to qualify for Europe again next season with a trip to Tottenham on Sunday afternoon, kicking off at 2pm
