Los Meringues are a massive 13 points behind League leaders Barcelona and we also dumped out of the Copa de Rey last week.
Cruyff, a Barca legend, says Mourinho can't keep living on past glories.
“His negative behaviour will always have its consequences. He thinks that his way of coaching is right and he justifies it by past results, but I believe it is wrong,” the Dutchman told Rac1.
Cruyff also feels that Madrid are now paying the price for not having a proper development system like the Blaugrana have.
“I am not surprised by what is happening at Madrid. This will always happen when your philosophy is to sign and gamble on big signings,” he adds.
“Homegrown players have more than just a contract with the club. They take the club to their heart. Transfers can bring in good players, but never for too long. Clubs need their youth system.”
