Johan Cruyff slammed Barcelona's performance in Sunday's 1-0 defeat at home by Real Madrid.
The former Barca coach rapped: "Madrid played as they know they can - and achieved the result they set out for. Barca played at home like they do when playing away - without intensity.
"Madrid have tightened their defence and played Barca on the counterattack. It's the tactics of a small club, but with players of Real's level it can be very dangerous.
"Barca should not blame the absences of players for the defeat.
"The enemy of Barca is not today the seven points that Real have on them; the enemy of Barca is Barca. If they do not recognise their faults, then they will not get another opportunity (to win the title)."
