Barcelona coach Pep Guardiola admitted that his side were taught a valuable lesson after their 2-1 defeat to Real Sociedad, which leaves them needing four points to win the title
Despite leading through a Thiago Alcantara goal, the Catalans experienced their first loss away from the Nou Camp this season after goals from Diego Ifran and a Xabi Prieto penalty.
"It is an important lesson that we were taught today. We have to play with our heads. We need four points and we must find where we can get them," he said in his post-match press conference.
"We are a team capable of winning or losing. We have come from a difficult situation with many players out. We competed well in the second half but we lacked sustained spells of possession. We did not have control of the ball."
Guardiola then turned his attentions to the upcoming Champions League semi-final second leg at home to Real Madrid on Wednesday.
"It is the semi-final of the Champions League. It is always better to be winning but we will analyse this defeat. We must now prepare for Tuesday's game.
"We have a good advantage in this semi-final but we need to ensure that our players recover. It will be a hard game in every way and should we overcome these difficulties, we will have more options when we reach the final."
