Miralem Pjanic is reportedly set to take over from Arthur and wear the No. 8 shirt at Barcelona next season.
According to Sport, the 30-year-old has already been handed his new squad number and will take over from the Brazilian.
Pjanic finally arrived at the Camp Nou at the end of last week and took part in training for the first time on Saturday.
The report claims Pjanic could join in with full training on Monday ahead of a possible debut on Wednesday when Barcelona play their second pre-season friendly against Girona.
