Tottenham remain on course to end their 17-year trophy drought and to win silverware in Ange Postecoglou's second season after a 2-0 win in Bodo/Glimt sent them through to the Europa League final.
Spurs held a two-goal lead after last week's first leg in north London, but had been warned to expect a stern examination on Bodo's notoriously difficult artificial surface in the Arctic Circle.
A firework display welcomed both teams onto the Aspmyra Stadion pitch, but Postecoglou watched his team produce a masterful defensive display in the first half before they struck twice in the second period.
Dominic Solanke made the breakthrough after 63 minutes with his 15th goal of the season before a cross-cum-shot from Pedro Porro six minutes later all but assured Tottenham of a place in the final in Bilbao.
It will be only the second European final Spurs have contested in the last 40 years and despite a woeful Premier League campaign with the club down in 16th position, Postecoglou can still stay true to his vow of always winning a trophy in his second season.
Tottenham boss Ange Postecoglou said his side had given the club's fans "something to dream about" after setting up an all-English Europa League final against United.
Postecoglou told TNT Sports: "I couldn't be prouder of the lads. We knew it would be a difficult place to come. We're well aware of the record they have here and the pitch and all those kind of things - the lads handled it really well.
"We fully deserved to win both legs to get though and we're excited, we're in the final.
"This is why we do what we do as much as anything else. You understand the context of what this football club has been trying to achieve for quite a while and managers and players come and go, but the one constant is the supporters.
"We've given them some hope, something to dream about. We've got an exciting trip coming up and a great experience and who knows? Hopefully we can do something special."
