Cristiano Ronaldo is one of the richest athletes in the world, a lot more so than you probably think. Since he started at Sporting Portugal and to now at Juventus, going through Manchester United and Real Madrid, the Portuguese has amassed an incredible pile of dough.This enormous fortune has allowed him to take care of the almost uncountable generations in his family, including his four children, Cristiano Jr., Eva, Mateo and Alana. Outside of family, though, these are the four main things that Ronaldo spends his money on:Luxury cars: It’s sort of a tradition for footballers. It’s not necessarily the fact that they like particularly fast cars, but let’s just say that taking a drive in a Renaut Mégane isn’t such a bad thing. Cristiano is no exception to the rule - driving a Lamborghini Aventador, a Rolls Royce and a Maserati. He's also reported to own a Porsche, a Mercedes and a Bentley.Holidays in paradise: Yeah, footballers earn lots of money, so obviously they need to have time to spend it. After scoring all those goals every season, Ronaldo does need time to unwind and relax, holidaying all over the world. Recently, he made waves in Greece by leaving behind an unbelievable tip.Charitable organisations: Ronaldo has always been big on charitable giving, regularly pouring astronomical amounts of money into good causes including children's charities Save the Children and the Make-A-Wish foundation.Real estate: Having money is good, having more money is better - so Ronaldo invests in properties in order to grow his considerable fortune even further. He lives in a luxurious million dollar villa in Madrid whilst he also owns a luxury apartment in Manhattan's Trump Towers and a football-themed hotel in his native Madeira.Whilst these are the main areas of spending for Ronaldo, he obviously spends plenty of money on other things too. Of course, we could have added his lawyer to this list, but that’s not really our style... Take a look at the video above to find out more about Ronaldo's spending habits!
