Harry Kane's secret successful 'side business' that has fetched him millions

But according to The Sun, the England striker is making plenty of cash through a property portfolio that has created with the help of his brother and agent, Charlie and parents.

The company is called 'Edward James Investments' and is believed to be worth £13.1million.

"Harry is as astute with his money as he is with his finishing," a source told The Sun.

"Lots of footballers make investments in property, with mixed results, but Harry clearly knows what he’s doing."

And although he owns a number of houses, it's said that the luxury property Kane and his family live is actually one they pay £1 million per year to reside in.

It's not uncommon for footballers to invest in property so that their money does not dry up when the time comes for them to hang up their boots.

Similarly, former Middlesbrough and Barcelona striker Martin Braithwaite invested $850,000 in a real estate business and partnered with his uncle, Philip Michael.

As a pair, they own real estate that is worth €250 million in the New York, Philadelphia, Jersey City and San Antonio areas and the company claim to have $300 million in assets under management.

Separately, City AM say Kane invested an 'undisclosed sum of cash' in low-calorie doughnut firm Urban Legend back in November, explaining that the company "connects with my keen interest to encourage others to look after their health and for retailers to have healthier options more widely available".
