Gianluigi Donnarumma has received a 100-pound fanella in Paris Saint-Germain after signing a transfer of parameters from AC Milan.
Italy's hero in Euro 2020 has signed a five-year contract with French giants and follows the additions of Gini Wiinalum, Sergio Ramos and Acraf Hakimi.
But 22-year-old was unable to choose his favorite number of fans in Parc des Princess.
Because he debuted with Milan as 16-year-old, Donarumma kept 99 after the year he was born.
However, the League One rules forbid goalkeepers from holding such a number, and they notoriously prevented Mario Balotelli from wearing No.45 in Nice and Marseilles.
Numbers 1, 16 and 30 are specially reserved for goalkeepers, but in this case they are occupied by Keylor Navas, Sergio Rico and Alexander Letelier, respectively.
Courtesy of a rough translation by Balls.ie, rule of LFP # 670 says: “Every Ligue 1 club and Ligue 2 has to place a list of the number assignments on Isyphoto 72 hours before the start of the race.
This list cannot pass 30 names, number 30 is the last on the list it can be filled out and updated with every movement in the club. If a club justifys the employment of over 30 professional players under contract, the board could provide an exception to the previous Paragraph. Strange calls are forbidden (executed: 45 - 82).
“Numrat 1, 16 and 30 are reserved exclusively and necessarily for goalkeepers. After all, the number 40 could be assigned. All teams must have a fan with a number 33 that is not assigned to a player and reserved for the collapse of replacements”
Incredibly, Donnarumma is now the ninth goalkeeper on the first team of SPG.
