The striker had played the first matches with number 16
The squad list to play Champions League used to discover that Sandro had changed number 16 for 19. The striker had played the first official matches with 16 but now he has decided to choose 19, number used for the last time by Ibrahim Afellay in 2013/14. We could see it because this Monday La Liga published a list of the numbers for the 2015/16 season. So the free numbers are 7 —which shall be used by Arda Turan starting on January,— 16 and 22 —used by Aleix Vidal in Sevilla, so the probable number he will take on January.
Sandro's favorite number is 9, used in the Barcelona Academy, despite using 19 in the last season in Barcelona B. Regarding matches with the first team last season, he used 29.
The striker aged 20 trusts in playing as much as he can when being able to replace Neymar, Suárez and Messi. For the moment, he has played 54 minutes in 4 matches.
