Barcelona suffered an emphatic 8-2 in Lisbon on Friday night as they bowed out of the UEFA Champions League quarter-final stage.
Pique, who has always been outspoken, was quite vocal in his frustration towards toward the club heirachy after the encounter.
“Shame is the word. You can't play like that, you can't play in Europe like that," the defender fired to Movistar after the game in Lisbon's Estadio da Luz.
"It is neither the first, nor the second, nor the third time. It's very hard, we all have to reflect.
"The club needs changes and I'm not talking about the coach, about the players. I don't want to point at anyone. Structurally we needs changes of all kinds, because it is neither the first, nor the second nor the third time.
"The first one to volunteer will be me, if new blood has to come in and change this dynamic I will be the first to go, to step aside.
"Now we have hit rock-bottom. I think we all have to look and reflect internally and decide what is best for Barca, which is the most important thing."
