The South Korean icon snapped backed at rumours regarding a big-money move for Spurs' prolific frontman, reiterating that he won't be drawn into gossip.
In a welcome boost for Spurs chairman Daniel Levy, Son Heung-min committed his future to the north London club and added that he is not panicking over the prospect of Kane leaving the fold.
Kane, who is gearing up for a Euro 2020 campaign with England, is said to be pushing a switch away from Spurs as he looks to land the major silverware that has proved elusive during his time at the club.
Asked whether he is concerned that Spurs could lose their talisman this summer, the Son Heung-min jokingly reponded: "Has Kane moved already?"
"Everything is not decided, rather than worrying about his transfer, I am doing my best at Tottenham," he continued.
"I want to focus on the national team and Tottenham - maybe Kane is doing the same, he is busy preparing for the Euros."
Spurs chief Levy does hold all the power though given Kane is tied down to a long-term contract until 2024.
But once the European Championships are completed, Kane will have to decide whether he stays or jumps ship.
In an exclusive interview with Gary Neville, the 27-year-old highlighted that he doesn't want to have any regrets once he calls time on his career.
"I don't want to come to the end of my career and have any regrets - I want to be the best I can be," he told Neville on The Overlap YouTube channel
"I never said I'd stay at Spurs for the rest of my career and I've never said I'd leave Spurs.
"People might say, 'he's desperate for trophies, he needs trophies', but I feel like I've still got almost another career to play."
