Tottenham will smash through their wage ceiling to give themselves the best chance of keeping record-breaking striker .
are already lining up a move for Kane, with Tottenham chairman Daniel Levy well aware of the growing interest.
Kane has become one of the most valuable players in world football but his relatively low wage of £110,000-per-week does not reflect his growing standing in the game.
However, Spurs are set to revisit Kane's contract at the end of the season with a view to offering him a fourth pay increase since August 2014.
Kane is the club's top earner and his bonuses are particularly lucrative. Consequently, given his prolific goal record and Tottenham's emergence as a Premier League force, the striker's salary will have been significantly topped up with further payments.
Levy has a history of rewarding his best players with regular pay rises provided they keep performing. Gareth Bale's contract was improved on a yearly basis before he joined Real Madrid for a then world record fee of £85.3million. However, Kane is thought to have a far greater emotional attachment to Tottenham than Bale had.
Kane is planning to mark his momentous 2017 with a special photograph featuring his eight hat-trick balls.
'At the minute, they're all stored away in bags,' said Kane. 'I still haven't got anywhere to display them. I'll have to talk to my missus and get a room for them somewhere. I'll have to get them out before the end of the year and have a picture with them. That will be a good one.
'It's just been a great year, with the birth of my daughter as well. It's been amazing, and hopefully 2018 will be even better.'
When his girlfriend Kate gave birth to Ivy Jane on January 8, Kane was already on the way towards his 56-goal haul with two in a 4-1 win at Watford on New Year's Day.
'It was a good start,' he said.
