Wolves were the first Premier League side to book their place in the last-16 of the Europa League as they saw off Espanyol 6-3 on aggregate.
Nuno Espirito Santo was afforded the luxury of resting some key players with a 4-0 advantage from the first leg and comfortably went through to the next round despite a 3-2 defeat on the night.
Espanyol opened the scoring in the 16th minute to give them hope of staging a mammoth comeback.
The hosts worked the ball down the left and Adria Pedrosa fired in a first-time cross for former West Ham striker Jonathan Calleri to finish off.
Espanyol’s hopes were all-but killed off when Adama Traore levelled for Wolves six minutes later.
Daniel Podence found the winger in the area, whose first touch ricocheted off the home defender and back, before squeezing into the bottom corner.
Wolves led 5-1 on aggregate and, with their away goal, meant the Spanish outfit needed five goals to progress.
Espanyol regained the lead from the penalty spot in the 57th minute with Calleri coolly slotting home his second goal.
Max Kilman was the culprit for a high foot on David Lopez, with Marco Guida pointing to the spot.
Calleri sent Rui Patricio the wrong way with the Spanish side needing four more goals to progress.
Wolves equalised once again with 11 minutes remaining to effectively seal their place in the Europa League last 16.
A quick throw-in caught out the Espanyol defence as Podence sprinted free down the left wing before firing a low ball for Matt Doherty to tap in at the far post.
Calleri then completed his hat-trick in added time to make it 3-2 but it proved too little too late.
