Napoli 2 Wolfsburg 2 (6-3 agg): Benitez moves closer to equalling Trapattoni's record
Rafael Benitez remains on course to become only the second coach to win the UEFA Europa League on three occasions after a 2-2 draw saw Napoli stroll past Wolfsburg 6-3 on aggregate
Having already won the competition with Valencia – in its previous guise as the UEFA Cup – and Chelsea in 2013, Benitez could match Giovanni Trapattoni's record after his Napoli side cruised into the semi-finals thanks to goals from Jose Callejon and Dries Mertens.
Wolfsburg dominated the opening half and could have wiped out their three-goal deficit in the first half but Ivan Perisic and Nicklas Bendtner both failed to take their chances.
Napoli made them pay five minutes after the break as Callejon converted a Gonzalo Higuain pass - albeit with the aid of a deflection.
The hosts were a completely different side in the second half and Mertens extended their lead after 65 minutes with a cheeky flick after Mariano Andujar had blocked his original shot.
A stirring fightback from the Bundesliga outfit saw Timm Klose and Perisic score in quick succession, but it was not enough to stop Napoli extending their unbeaten home run in European matches to 12 games.
Wolfsburg got the quick start they wanted and could have been ahead on the night inside the opening minute.
Daniel Caligiuri raced down the right and delivered a teasing cross into the penalty area for Perisic – one of five changes – who poked goalwards only for Andujar to claw the ball away.
The visitors were playing with a freedom brought out by their demoralising first-leg defeat, but as in Germany seven days earlier they struggled in the final third.
As Napoli failed to find any momentum, Wolfsburg wasted a second chance to give themselves a lifeline after 32 minutes, Bendtner rising above Raul Albiol but heading the wrong side of Andujar's right-hand post.
The former Arsenal striker did much better with his next effort in the closing minutes, firing low towards the bottom-right corner only for Andujar to pull out a good save with his left hand.
Wolfsburg's wastefulness in front of goal was punished early in the second half as Callejon controlled a pass from Higuain and fired into the top-right corner, albeit with the aid of a deflection off Ricardo Rodriguez.
Mertens doubled Napoli's lead with 25 minutes remaining as he flicked home after Andujar had saved his first effort from a superb Higuain knock-down.
With Napoli appearing set for a comfortable end to the tie, Wolfsburg finally found their finishing skills as Klose and Perisic netted to bring them level on the night.
Klose rose majestically to head home a Max Arnold corner after 71 minutes, and from the visitors' next attack Josuha Guilavogui crossed for Perisic to nod past Andjuar from close range.
The goals saved some pride for Dieter Hecking's side, but it is Napoli who progress to the last four as they look to lift the trophy for the first time since 1989.
