Former Chelsea boss Luiz Felipe Scolari claims the successor to sacked Andre Villas-Boas will face "hell" at Stamford Bridge.
Villas-Boas was axed by Roman Abramovich less than a year into his tenure, but he is not alone in being unceremoniously dumped by the Blues' Russian owner.
Scolari went the same way in 2009, while the likes of Claudio Ranieri, Jose Mourinho, Avram Grant and Carlo Ancelotti were all shown the door by Abramovich.
Roberto Di Matteo has been placed in control of team affairs until the summer, but the search for a new boss is already underway - with Josep Guardiola, Rafa Benitez and Mourinho in the frame. And whoever is appointed has been warned of the perils they will face under Abramovich.
"England has clubs like Arsenal, where Arsene Wenger has been for several years, yet has won only two or three championships," Scolari, now in charge of Brazilian outfit Palmeiras, said. "Chelsea's culture is different, but this move is strange - although it's not so strange to me because of what I went through there.
"Some things are known, like the relations with the chairman, who has the relationship with some players before the coach.
"Villas-Boas was a champion and he will continue to be. He needed to replace at least seven or eight players, even since I was there, but he failed.
"It will be hell for whoever succeeds him."
However, Ray Wilkins, who was controversially fired as Carlo Ancelotti's assistant at Chelsea in November 2010, has leapt to the defence of the players and the possible role they have played in the sacking of managers.
"I found the players an absolute delight to work with," Wilkins told talkSPORT. "They are a very nice bunch of guys, they are a hard-working bunch and, coupled with that, they are an extremely talented bunch. We didn't have a problem.
"I don't think the players swayed the owner. It appears they are looking for change at Chelsea and I just feel they went about it too quickly with AVB.
"To change what has been such a force - not only in the Premier League but in European football - overnight, you just can't do that.
"It takes a gradual adjustment. Chelsea have gone hammer and tongs at it and they should have taken their time in switching over.''
