Barcelona threw away a 2-0 lead and saw their La Liga hopes receive a major setback as they drew at Levante.
“There are very few options for us to win the league now,” Sergio Busquets said.
“It feels terrible. We weren’t able to win the game, we started well, got the advantage and the second goal, but could not get a third. As has happened too many times, errors have cost us.
“The point means very little to us. We weren’t precise with our passing and they took full advantage. We had our chances but we paid for our mistakes – we’ve not had a good second half.
“It is our fault and we take responsibility – we allow teams to score too easily against us.”
“In the second half we lacked intensity and I don’t know what I did wrong at the half-time period as we were superior in the first half,” said Koeman.
“They surprised us by scoring three goals and I have no explanation – I don’t know why it happened.
“In terms of intensity, we dropped and got over-relaxed. The whole team defensively was not at the level required. Conceding three goals in 45 minutes is too many for this team.”
