Wolfsburg repelled a string of Sporting Lisbon attacks to reach the last 16 of the Europa League with a goalless draw in Portugal.
With a 2-0 aggregate lead from the first leg, Wolfsburg focused their efforts on keeping Sporting at bay and could thank goalkeeper Diego Benaglio for making a string of saves to frustrate the hosts.
The match was slow to get going but came alive in the second part of the first half as Sporting created a number of chances.
Nani's powerful shot went wide before William Carvalho's effort was held by Benaglio.
Paulo Oliveira then headed over the crossbar while Junya Tanaka fired wide.
Carvalho did find the target with a long-range effort in the 37th minute, but Benaglio turned it behind before Wolfsburg managed to block Tobias Figueiredo's header from the following corner, with Naldo hoofing it clear.
Benaglio then made a double save, first denying Tanaka and then Adrien Silva on the follow-up. The ball fell again to a Sporting player, but Joao Mario blazed over.
Wolfsburg had barely been seen as an attacking force, but as half-time neared, Andre Schurrle pounced on a lose clearance from Tanaka to fire at goal, but Rui Patricio was equal to the shot.
Sporting were quickly on the attack again in the second half, but Tanaka missed the target, and Nani fired straight at the goalkeeper.
Instead it was Wolfsburg who should have taken the lead in the 54th minute, but Kevin de Bruyne saw his drilled shot bounce back off the post.
Back at the other end, Benaglio used his feet to deny Nani as Sporting continued to squander chances.
Andre Carrillo fired over while Islam Slimani's close-range header was blocked by Bas Dost.
In the 77th minute, Benaglio made a brilliant save to keep out Tanaka's powerful shot shot from close range, and Sporting were out of ideas, allowing Wolfsburg to see the game out and ease into the last 16.
