Spurs went into their game against the Canaries looking to take their win-streak in England's top tier to three games.
And they took the lead after just 10 minutes thanks to Lucas' brilliance.
The Brazilian found space roughly 25 yards out after some brilliant build-up play with Son Heung-min.
Lucas flicked the ball around a defender before playing a one-two with his South Korean teammate.
Lucas beat another player and then unleashed a thunderbolt that went past Norwich's Tim Krul in a flash.
That was just Lucas' third goal of the season and his first Premier League goal of the campaign.
What a way to open his account in England's top tier in 2021/22.
Divock Origi does it AGAIN! Late winner as Liverpool beat Wolves! Full reaction on The Football Terrace...
Antonio Conte's side eventually cruised to a 3-0 victory in front of their home fans.
Davinson Sanchez doubled Spurs' lead in the 67th minute, before Son put gloss on what was a great day for the north London outfit 10 minutes later.
The three points means Spurs have leapfrogged fierce rivals Arsenal into fifth place.
They are now just two points off a Champions League berth and will move into fourth should they win their game-in-hand.
