Barcelona president Josep Maria Bartomeu has slammed Arthur for refusing to return to the club and has accused the Brazilian of “disrespecting” his team-mates.
The midfielder has remained in Brazil and is refusing to play for the club again after becoming unhappy at being frozen out at the Camp Nou.
Bartomeu made it clear he thinks Arthur’s actions are “unacceptable” and explained why Barca will be taking disciplinary action against the 23-year-old.
“What Arthur has done is an insult to his teammates, because the team wants to do well in the Champions League.
