Barcelona coach Xavi admits they were poor for defeat at Girona.
Barca were hammered 4-2 in last night's Catalann derby.
Xavi said: "The truth is that we have lost control of the game due to flagrant errors that cannot be. It keeps happening to us. We had the game to decide and we gave it away.
"It is a carbon copy of the Madrid game, of the other Girona game. We have to change a lot to compete next year. Today I am sad and disappointed. We have seen both sides of the coin. Brilliant until the 60th minute, then it is the summary of the season: the lack of effectiveness kills us.
"We arrived easily but we lack force. and be more effective. And then we make blatant mistakes that do not correspond to the level of the players and the club. And any blow costs us a lot. many footballers. I am very sad and disappointed.
"It's a shame. We collapse in any negative situation. They are specific errors. We have given all the confidence to the players, but this is very difficult. It is also a lack of maturity. I hope next year to compete better, because that is practically how it is.
"It doesn't show on the scoreboard when we are superior, we had control of the two games against Real Madrid and Girona, and they slipped away from us."
