Zinedine Zidane's tactics for Real Madrid's El Clasico win over bitter rivals Barcelona have been leaked to the Spanish press.
Los Blancos won at the Nou Camp despite trailing 1-0 and having a man sent off.
Gerard Pique opened the scoring before Karim Benzema equalised in the second half; Sergio Ramos was then sent off for a second yellow card with just under 10 minutes remaining but Cristiano Ronaldo scored a late winner for Zidane's side.
The instructions, which are written in blue and red ink on Real Madrid headed paper, place emphasis on Barcelona's high pressing system and the importance of stopping Ivan Rakitic and Andres Iniesta dominating the midfield - the reason is to make the home side play on the wings rather than through the middle.
Lionel Messi and Neymar were to be followed by a centre-back when either dropped deep, meaning defensive midfielder Casemiro would have to drop back to cover, while Real were told to be wary of Luis Suarez's diagonal runs.
