Derivatives: Thanks to the Mbappe, Neymar, Cavani trio replaced by the Mbappe, Neymar, Messi trio, PSG sells more than a million shirts a year. E. The results It seems complex to model by a typical financial mathematical function as the variables are numerous. [...]

[...] Thus, the advantage of using the quantitative approach is to objectively estimate the value of a player without taking into account the non-sporting hazards (TV rights negotiated on the rise, for example). Moreover, having a wide range of precise data on the athlete's aptitudes during training or competitions would potentially be an opportunity to positively impact his progression curve. This is why precise tools for measuring sports performance are necessary. B. How to quantify sports performance What interest? Emphasize the sporting value of a player in relation to his general market value and assign a numerical value to the skills that can be incorporated into the estimate of his market value. [...]

Regularity, i.e., the ability to repeat good performances and possibly score goals: An irregular player will naturally be undervalued compared to a regular player in his performance. [...]

[...] Moreover, for the latter, a secondary market (similar to the financial markets) called "the signature bonus" comes into play. It is up to the requesting clubs to offer the free player an attractive package, with the added value of a net bonus, in the event of signing a contract.
