Luis Enrique has criticised his Barcelona players for failing to adhere to his instructions against Real Madrid.
Barca striker Luis Suarez opened the scoring at Camp Nou, but Blancos defender Sergio Ramos equalised in injury time with a header following a free kick.
The first El Clasico of the season ended 1-1, and Enrique was upset by the fact that his team had failed to follow his gameplan and now find themselves six points behind their rivals in La Liga.
"The instructions were very clear, do not give away fouls especially if a Madrid player has his back to goal," he told reporters after the game.
"It is a six-point gap, this isn't where we wanted to be, we could have closed this match, we had it in hand but have somehow failed to take the win."
Next up for Barcelona is their final Champions League group match at home to Borussia Monchengladbach on Tuesday night, before returning to La Liga action with a trip to Osasuna on Saturday afternoon.
