The choice of number for Mora is historic, as it makes Roma the first team to have used all numbers from 1 to 99 at least once in their history. The Italian league is known for its more flexible rules regarding shirt numbers, compared to leagues with stricter regulations like La Liga. This has allowed Roma to combine classic numbers like 10 and 16 with higher and more striking numbers like 92 and 99.

Roma have a long history of experimenting with different shirt numbers, and have had players wear numbers from 1 to 99. Examples of players who have worn these numbers include Wojciech Szczęsny, Cafu, Roger Ibañez, Radja Nainggolan, and Romelu Lukaku. The team's willingness to try out different numbers has been a key factor in their ability to create a unique identity.

Mora's signing is the latest example of Roma's willingness to take risks and try out new things. The 86-year-old striker will be looking to make a big impact at the club, and his historic number will be a reminder of the team's commitment to innovation and creativity.
