Paris Saint-Germain

Paris Saint-Germain is not the world’s most supported football club but in France, it is the most popular one with 22 percent of all the nation’s football fans being their supporters. This club has a fan base of 35 million. However, other sources claim that the number may be doubled: something around 70 million. In their first three years of formation, Paris Saint-Germain was a fan-owned club with around 15,000 members having paid an annual fee of 25 to 40 francs to hold up the club.

Unluckily, PSG fans have a long history of hooliganism with even one murder case in 2010 when a fan named Yann Lorence was killed in a clash with Marseille fans.

PSG has more than 40 million follewers on Facebook, 29 million on Instagaram, and 7.7 million on Twitter. Famous people including the former French president, Nicolas Sarkozy, former top Belarusian tennis player, Victoria Azarenka, and former NBA player, Tony Parker, and celebrities like US rapper, Tyga, Kim Kardashian, Naomi Campbell, and Rihanna, are all PSG fans.

Liverpool

A study published in 2015 showed that Liverpool with 580 million supporters are the second football club after Manchester United having the highest number of supporters in the world. But real numbers may be different. Some other sources claim that the number is just more than 70 million. Liverpool also has 300 official fans clubs in more than 90 countries all around the world, according to their official website. Like PSG fans, Liverpool fans have a long history of hooliganism behind them, too.

Liverpool has near 37 million followers on Facebook, around 26 million on Instagram, and only 450,000 on Twitter. Many celebrities and famous people are Liverpool fans, including the American actress and Brad Pitt’s wife, Angelina Jolie, the famous English-Irish singer and song writer, Chris de Burgh, WWE wrestler, Sheamus, hip-hop pioneer, Dr. Dre, UK’s big comedian, John Bishop, and Hollywood actor, Liam Neeson.
