Football and money go hand in hand in the 21st century, with players across the globe being bought and sold for tens of millions of pounds on a regular basis. Often these transfer costs are based on what both the buying and selling club consider to be the player’s market value.
The CIES Football Observatory, a company that looks at the scientific evaluation of professional players' transfer values, has revealed its list of the 100 most valuable players in the world today. The CIES Football Observatory says it calculates these values through multiple factors such as the clubs’ characteristics, time, contract length, previous fees, performance, player’s characteristics and popularity.
