The centre-back spoke to Movistar after the match and said he’d be willing to leave if the club decides a fresh start is needed for next season.
“Shame is the word. You can’t play like that, you can’t play in Europe like that,” he said.
“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.”
It seems inevitable that manager Quique Setien will be the first to leave. The 61-year-old only arrived in January but his position looks untenable after such a humiliating performance again in Europe.
