Real won the first-leg of their Champions League round of 16 1-0 against ten-man Atalanta in Italy.
But Pedrerol said on El Chiringuito: "They have won... then there is the critical Madridista who liked them to go like at the Bernabéu, used to seeing their team score several goals.
"And today we have seen a Madrid going on the defensive, holding the result. This is how (Zinedine) Zidane got the league title. The formula is clear and that's what the Frenchman came out for today.
"With the dismissal of Atalanta, Madrid has played against 10 for 75 minutes, and not much. Congratulations, but you have to ask for more. And those who ask for more I am not less from Madrid, we are more demanding."
