It could be argued that the Tottenham Hotspur hitman is actually priceless.
The 25-year-old is arguably the best out-and-out striker in world football at the moment, and he seems to just keep getting better and better.
Kane has racked up an incredible 160 goals in 243 appearances in all competitions for Spurs, and if Mauricio Pochettino's men are to have any chance of winning either the Premier League or the Champions League in the foreseeable future, they will need to keep hold of the England international.
Many of Europe's most prestigious clubs will surely be keen to prise him away from north London, but Tottenham hold all of the cards, with his contract not due to expire until the summer of 2024.
Despite Kane's importance to Spurs, he is not priceless, according to Spanish media outlet AS at least.
They suggest that Tottenham have slapped a €350 million (£312 million) price-tag on the 25-year-old's head, and that surely makes him unattainable for any club in world football.
That's what Spurs fans will be hoping anyway.
Selling Kane, even for an astronomical amount, would set a very dangerous precedent for the north London outfit, and Pochettino and Daniel Levy must do everything within their power to keep hold of him.
