At 25, Three Lions captain Kane is not thinking too seriously about retirement yet, but he now insists that he will not quit sport altogether when the time comes to hang up his boots.
A long-time NFL fan, Kane travelled to Atlanta in February to watch his beloved New England Patriots defeat the L.A. Rams to seal Super Bowl glory.
And Kane now has his eyes on becoming an NFL kicker in the future, believing that doing so could see him go down as one of the greatest sportsmen in history.
"[The desire to play in the NFL] is real," he told ESPN. “Something that in 10 or 12 years I definitely want to try.
"It goes back to that drive to be the best. Even if I download a game on my phone, can I be the best in the world?
"If you play in the Premier League and the World Cup and you then play in the NFL, would you then be considered one of the greatest sportsmen ever?"
Kane's NFL hero is six-time Super Bowl-winning quarterback Tom Brady, with the 41-year-old deemed by many to the best football player of all time.
Despite not being marked for greatness as a youngster, Brady has developed into the most successful player the game of American Football has ever seen.
And Kane - who spent time out on loan with four different lower league clubs before becoming a regular in the Tottenham first team - sees similarities in his own career path to that of Brady's.
"Not many people thought he’d become that good, or even play in the NFL, and he went on to become the best ever.“
"At the time, it gave me a real boost to say, look, anything is possible. If you have that self-belief and that drive and that hunger, you can do it."
While playing in the NFL might be a dream for Kane in his future, right now he must concentrate on spearheading Spurs' fight for a place in the top four of the Premier League.
