Gerard Pique says big changes are needed at Barcelona following their "humiliating" 8-2 loss to Bayern Munich in the Champions League quarter-finals.
The 33-year-old defender, who has won 20 major titles over 12 years with the club, added that he would be "the first to leave" if the club wished it.
Friday's loss was the heaviest Barca have suffered in Europe and ends a season that has also seen them lose the La Liga title to Real Madrid.
"We have hit rock bottom," said Pique.
"This is not the first, nor the second, nor the third time. We are not on the right path."
He continued: "Coaches and players follow one another, but it has been several years since we have been able to be competitive on a European level.
"We all have to think internally and decide what is best for the club, for Barca. Tonight was unacceptable for Barcelona.
"It's very hard to take but I hope it will be useful for something, for us to all think about it.
"The club needs changes. And I'm not talking at the level of the coach or the players, but structurally the club needs changes of all kinds.
"We must bring in new blood to change this dynamic, and if necessary, I would be the first to leave.
