CIES assesses players' transfer value based on many factors such as age, contract duration and performance. It has been estimated that the total value of all players in the five largest men's leagues (England, Spain, Italy, Germany and France) will fall from EUR 32.7 billion to EUR 23.4 billion during the period 11 March to 30 June .
For example, Manchester United midfielder Paul Pogba has been taken. Assuming that no matches are played and no contracts are extended during the said period, his value would fall from EUR 65 million to EUR 35 million.
Of the clubs, French Marseille will suffer the worst. The value of their squad is expected to decline by as much as 37.9 percent - from EUR 256 million to EUR 159 million.
Among those most affected by the corona crisis are also the major clubs Inter, Bayern Munich and Real Madrid.
