Barca were shocked by Valencia at the Nou Camp.
We scored a goal, we had control and then we were predictable," said Dani Alves after the match against Los Che.
"We let three points slip away when we had the match under control," continued the Brazilian, who admitted that his team "gave away opportunities to a rival that didn't have mercy."
Alves added: "We lost and now we have to pick ourselves up. There's no time to feel sorry for ourselves."
The Brazilian isn't concerned with losing the top spot of La Liga: "You lose the lead at the end of the season, not now."
