The 21-year-old striker has been sensational for Mauricio Pochettino's side this season, netting 20 Premier League goals to date and earning himself a nomination for the player of the year award.
And England Under-21 coach Southgate believes the engagement with fans a homegrown player like Kane creates is something other clubs will crave.
Tottenham have it, with fans regularly singing songs in Kane's honour at White Hart Lane as the young striker produces the goods for Pochettino's team.
Southgate said of Spurs to the Mail: "I think all clubs deep down want what is happening at Tottenham, where you've got 30,000 people singing 'He's one of our own' about Harry Kane. It's really powerful for engagement with the fans."
Tottenham drew 2-2 at Pochettino's old side Southampton on Saturday afternoon, with Kane not particularly shining thanks to a superb marking display from the likes of Jose Fonte and Maya Yoshida.
The result leaves Spurs sixth in the Premier League - a point above the Saints but seven off the top four.
The north London side's youth is certainly something to be proud of this season, though, regardless of where Tottenham finish in the table. Especially that man Kane.
