According to research from the CIES Football Observatory, Cristiano Ronaldo is the 49th most valuable player in the world.

CIES say their assessment "takes into account the key criteria used by market actors such as age, position, contract duration, performance and international status." 

CIES' valuations have Paris Saint-Germain's Neymar atop their list at €213 million, followed by Barcelona's Lionel Messi on €202.2 million and Tottenham's Harry Kane third on €194.7 million.

An alternative list of the world's most valuable footballers on Transfermarkt.com has Ronaldo still joint third with Kane on £108 million.
