Murillo became the 13th player to wear Barca's no. 17 shirt.

Murillo, who has been on loan from Valencia, has become a member of Barca's first team, strengthening the depth of the squad, particularly addressing the shortage of defenders in the backline.
Murillo opted for the number 17 shirt. The number has belonged to Paco Alcazar for the past two seasons, and the number 17 shirt that has been vacant since his departure this summer now belongs to Murillo.
Since last season's 90s La Liga restructuring, a total of 12 players have worn Barca's number 17 shirt, with Murillo becoming the 13th man. The first owner of the number was Nigerian talent midfielder Amunic, who joined Barca from Atletico and spent a year for Them in the 96/97 season.
The second owner of the No. 17 shirt was Serades, but he only played in European games with this number. Before the turn of the century, the third and last owner of this jersey was Bogard.
Entering the new century, the No. 17 shirt welcomed 9 owners, the most familiar names by Barca fans are Mendietta, Van Bommel and Pedro. Barca's first-team active player Munir also crossed the number.
Here is a list of 12 number 17 jersey owners:
