#4 Better payday
Harry Kane signed a contract back in 2016 tying him down to Tottenham till 2022, which sees him earn £120,000 every week. With all due respect to Tottenham, but, by the current industry standards, that is a subpar figure.
To put it into perspective, Cristiano Ronaldo earns a staggering £365,000 a week at Real Madrid and Lionel Messi reportedly earns an astonishing £500,000 a week at Barcelona and Harry Kane outscored both of them in 2017!
Not to say that Kane is motivated by money, but there's no denying that money is an ever-present power and motivator in today's game. If Kane were to move to Real, he could see his salary double at the very least if not more. Such a substantial sum of money could possibly allow for a change of mind on Kane's behalf.
