Champions Barca let slip a two-goal lead to draw 2-2 at Real Sociedad and Real Madrid capitalised with a 4-2 home win over Getafe that was not as comfortable as the scoreline might suggest.
"They talk of a league of only two teams and this shows contempt to the others who are doing better and better and demonstrating their desire to beat us," Barca coach Guardiola told reporters in San Sebastian.
"It's a good lesson for the future. Sociedad's goals arrived when we were playing our best but it shows that in football you always have to be completely alert."
"Maybe the players were drunk on too much information and news about how easy the league would be and in the end it made things complicated," the Portuguese told a news conference. "All these teams that are supposed to be bad I don't agree.
"All of them are professionals, the coaches and the players. For me all the matches are tough.
"Throughout the season you'll get a few 5-0s or 6-0s but there are going to be difficult games. We will definitely drop points," added Mourinho.
