Considering the aggregate score heading into the fixture, Tottenham were always the favourites to progress.
Their professional display meant they made light-work of their opponents as they now await the draw to see who they will play in the next round.
Story of the game
Going into this fixture with a 4-1 advantage from the first leg, the tempo was as to be expected, with Tottenham controlling possession.
In the early stages, Wolfsberg pressed relatively high up the pitch, in an attempt to win the ball in the attacking third, but to no avail.
Steven Bergwijn started the game in lively fashion, driving at defenders with confidence, trying to make things happen - perhaps intent on ending his goal drought.
It didn't take long for Spurs to open the scoring through Dele, the almost forgotten midfielder scoring a wonderful overhead kick to give his side the lead.
The ball bounced invitingly into the air, following Dele's first touch from a cross, and he adjusted his body to acrobatically finish in a similar fashion to Olivier Giroud's goal last night.
Following the opening goal, the game went flat for periods of the first half, with neither side creating chances and a lot of sideways passing.
Dele was the most impressive player on the pitch, showing constantly for the ball with good movement and looking to put balls in dangerous areas.
Spurs should have doubled their advantage late in the first half, with Vinicius guilty of missing two good opportunities.
His first was a header, sent over the bar, after a good delivery from Matt Doherty.
Vinicius did well with the second chance, taking the ball round the keeper, but his effort was cleared off the line - had he squared it to Dele it would have guaranteed the ball in the back of the net.
Similarly to the first half, the opening stages were more exciting in the second-half, with Eric Dier perhaps lucky to remain on the field.
He would have been relieved to see the referee waive away appeals when Cheikhou Dieng went down under his challenge while through on goal.
Almost instantly, Tottenham went up the other end and doubled their advantage, with Vinicius getting his head on the end of a brilliant Dele cross.
Again, in a pattern reminiscent of the first half, the run of play winded down to a lot of safe passing and little chance creation.
Bale added the third goal in classic fashion, with a first time finish from Dele's astute pass, he bent the ball wonderfully into the top corner on his favoured left foot.
While Spurs keeper Joe Hart was little more than a spectator, the fourth goal conceded by Manuel Kuttin, was down to his defence being indecisive in possession.
They couldn't handle the press and Vinicius rounded off an impressive night with a calmly placed finish.
Dele Alli shines
Having been frozen out of the Tottenham set up for large periods of this campaign, Dele has been limited to just a handful of starts this season.
He was instrumental in the performance tonight, recording a goal and two assists, with all three passages of play showcasing his talent.
His movement was perhaps the most impressive feature of tonight's performance, he was constantly coming towards the ball and attempting to find little pockets of space in between the lines.
As his Spurs career looked in doubt, with a move away from the club making the headlines during the January Window, it is good to see him featuring more regularly in Mourinho's plans.
With crucial fixtures to come, performances like these will put him above his teammates in the pecking order for the Premier League fixtures to come.
Vinicius enjoying the Europa League
With his appearances mainly restricted to the cup competitions due to - to put simply - Harry Kane, Vinicius has impressed when given chances.
His brace today made it a remarkable six goals and three assists in six Europa League games, with only five being starts.
It remains to be seen how long he remains a fixture in the Europa League starting XI, before the likes of Kane and Heung-Min Son are drafted in.
Spurs' new found 'Mr Europa League' may only be at the club for this season, but his contributions could play a major factor in the quest for silverware this season.
Youngsters get a taste of first-team football
It was a night to remember for 20-year-old Marcel Lavinier as he made his professional debut alongside fellow academy product, 17-year-old Nile John.
Right-back Lavinier replaced Doherty around the 70-minute mark and looked sound throughout his small cameo.
John replaced Moussa Sissoko late on in midfield, a reminder that hard-work at youth level doesn't go unnoticed, if you are good enough you are old enough.
Recording his first goal contribution for the first-team, Dane Scarlett made himself the first 16-year-old to register an assist in the competition, since none other than Kylian Mbappe.
He is highly rated by Mourinho and the team at Tottenham, so eyes will be firmly fixed on his progress as he rises through the ranks, despite his young age.
