And, although United's Wayne Rooney had the honour of grabbing the final goal at the Lane, it was Kane's strike early in the second half which proved decisive as Tottenham - who had taken a first-half lead through Victor Wanyama's header - deservedly claimed maximum points.
Supporters swarmed the field as the final whistle blew but eventually returned to their seats to watch 48 former Spurs players each come out to rapturous applauds.
"It was a flawless performance and we deserved that victory", he said.
As confetti showered the pitch, a rainbow emerged over the sun-kissed golden cockerel atop the East Stand.
Dozens of club legends, including Martin Chivers, Glenn Hoddle, Ricky Villa, Ledley King, David Ginola, Dimitar Berbatov and Robbie Keane all took part in the celebrations. Gascoigne chose not to attend for health reasons. That's progression from last season and we have to keep it going now. "I think I am very lucky guy because to share the history of such a club in that special moment is so lucky to be here", Pochettino told a postmatch news conference.
It was a flawless performance and I am happy for the victory for our fans.

"But we have one (the Europa League final) that is more important than others".
"When the new era and stadium arrive there will be different expectations, but, most important, always in our memory will be White Hart Lane, the soul and the smell. Now is the time to look forward".
"To sign off with a win against a tough team like Man United is special".
"Everything is heading in the right direction, but we've got to go out there and do it". "We are not moving", Levy said.
Notable signage from around the stadium and artefacts such as old shirts, trophies and images on display in hospitality lounges and cabinets have been removed and retained for storage. Our new home will slowly embrace and engulf the old one. "It is great to achieve second position, we have been unbeaten at home all season so there are a lot of things to be happy about".
While Tottenham rejoiced, it was a sobering day for United who are now likely to finish sixth in Jose Mourinho's first season in charge - a place below where they finished under Louis van Gaal last season.
