The Brazilian side were thrashed by the Blaugrana on Friday evening at Camp Nou, and the former players have insisted that it was ‘humiliating’.
“I’m gutted! I’m really, really angry about it,” Coutinho told Globoesportes.
“No one likes to see that type of thing. It was humiliating.
“The President, the Coach and a number of players need to go.”
Pepe meanwhile admitted it was a sad day for the Peixe.
“They got a hiding. In our era, it was Santos who handed out these scorelines.
“Barca did as they pleased. With our history and tradition, it’s very sad.
“I knew that it would be a difficult match, but I never imagined that it would be a tragedy.”
