Guardiola, who led the Catalan club to three La Liga titles and two Champions League trophies between 2008 and 2012, insisted that Barcelona should move on quickly from the loss and look ahead to the league and cup fixtures that are lined up.
"There is a tendency in football to throw everything up in the air," added Guardiola.
"This industry is so difficult. [Barça] have lost a final, OK, congratulations to the opponent and now learn from it. Madrid scored quickly, defended well and were the better team, that's it."
