Barcelona star Deco believes his team-mates have to "ask themselves questions" after their Champions League exit at the hands of Manchester United completed a disappointing season.
Paul Scholes' 14th minute thunderbolt gave United a 1-0 win on Tuesday which was enough to send the English side to the final in Moscow after last week's goalless draw at the Nou Camp.
The exit heaped more misery on the Catalans, with the team already out of the race for La Liga, and Deco has slammed his team-mates for not living up to expectations.
"It's been a sad season, a season where Barca have suffered a lot," he said.
"It's complicated to understand why we haven't done better, especially looking at the team we have.
"When you don't win anything with a team like ours, you have to ask yourselves questions.
"We might have reached the semi-finals but we had to go through. We should have gone through with the team that we have.
"Now we have to have courage and responsibility because we had to get to the final."
Barcelona, who are third in the Primera Liga, have not won anything since 2006, when they completed a glorious season by winning the Spanish title and the Champions League.
And for Deco, who triumphed in Europe's premier club competition for the second time after collecting a winners' medal with FC Porto two years previously, another season without silverware is just not good enough.
"For a club like this it's difficult to go two years without winning anything," he added.
"I think that each player has to take his share of the blame and we all have to think about what happened so that next year the same thing doesn't happen.
"We have to talk about the problem inside the dressing room.
"But I don't want to talk about changing Barca, we have a good team with young players who soon will return to winning."
Barca travelled to Old Trafford knowing they only had to score as many as United, given the away goals rule.
The Catalan giants were perhaps the better side on the night and over the two legs, but they could not break down a gritty, determined United defence which has kept 30 clean sheets in the last 53 games.
Barca have now failed to score in four games on the spin - a statistic goalkeeper Victor Valdes blames for his side's exit.
"What matters is to get to the final, not to be better or play well," he said. "It's a real pity we couldn't score.
"But we found ourselves faced with a Manchester team very tight defensively and we couldn't. They had the luck when a great chance presented itself to them and they took it sweetly.
"They're little details. They got this goal early, we had to go on the attack, they tightened up very well and we couldn't do it."
Vales was also quick to point out that while Barca have endured a disappointing season by their high standards, the team can still be proud.
"We are out of the Champions League but we can really hold our heads up high because we gave it our all," he added.
"We're only out because of a great goal by Scholes which really pushed the tie in favour of United.
"It's normal that our fans are fed up and disappointed. We are the first to be upset because we really thought we could do it.
"Now we have to continue and try to finish La Liga in the best possible way and win the remaining games."
