Famous football manager Vyacheslav Zakhovailo explained how Transfermarkt determines the value of football players.
— With the help of a certain algorithm. All young players who are just entering professional football have about the same price tag — 50-100 thousand euros. Then the club for which the player plays, his marketing potential, the level of competition, the number of minutes played on the field, active actions, and so on are taken into account. Summing all this up, over time a virtual value of the player is formed.
But it usually has nothing to do with the real facts of buying and selling. Football marketing is based on whether there are willing buyers for a certain player and how many. That is when his value significantly increases and stops at the mark under which two clubs put their signatures in the contract, — said Zakhovailo.
