Luiz Felipe Scolari claims a number of Chelsea players did not respect him and his training methods during his ill-fated eight-month stint at Stamford Bridge.
The 60-year-old Brazilian, who is currently coaching Bunyodkor in Uzbekistan, singled out the behaviour of Ivory Coast striker Didier Drogba, Germany midfielder Michael Ballack and Czech Republic goalkeeper Petr Cech as unacceptable.
Scolari, who took over the Blues hot-seat last July and was sacked in February, told O Globo newspaper: "The people sacked are always the coaches. The main players already know this. That was my problem at Chelsea. Drogba, Ballack and Cech did not accept my training methods or my demands."
He added: "The real owners of football at the moment are the players. The coach, in most European clubs, has no strength to contradict them."
The former Brazil and Portugal boss, meanwhile, believes Cristiano Ronaldo will get on well with fellow Real Madrid new boy Kaka but reckons Raul is still the main man at the Bernabeu.
"Kaka is a strange player because of what he does both on and off the field," Scolari said of his countryman.
"That guy is a strange jewel. Despite having gained big fame and money, he keeps doing his best on the pitch like a youngster.
"I am sure Cristiano Ronaldo and he will get on very well with each other. Cristiano has nothing to do with the conceited image everybody has of him. I think both of them will be big friends.
"The problem Real Madrid have is Raul. He is a veteran and is still the boss in the dressing room, so woe betide anyone he doesn't like - including the coach."
