Johan Cruyff has declared that Jose Mourinho will ultimately fail to reproduce his success at Chelsea because of a negative attitude hardened in La Liga.
Mourinho was appointed as Blues coach for a second time yesterday, signing a four-year contract at Stamford Bridge.
Former Barcelona boss Cruyff has predicted that Mourinho's second spell in West London will end without silverware, basing his opinion on the Portuguese coach's work at Real Madrid last season.
He told The Sun: "Mourinho will never win a prize again. I think that because of the way he acted in Madrid. He blamed everyone and everybody when something went wrong in Madrid.
"And he is playing games with people who are working there. Mourinho himself played an unbelievably negative part in his Madrid years. First he moved out general manager Jorge Valdano and later he did the same with director of football Zinedine Zidane.
"And in the end he dropped Iker Casillas, the captain of the Spanish national team. This behaviour does not work in football, it only works in paralysing the dressing room. That's why it didn't work out in the end in Madrid and that's why I think Mourinho will not succeed any more."
The 50-year-old will be officially unveiled as Chelsea manager at a press conference on Monday.
