Luiz Felipe Scolari says Andre Villas-Boas' successor at Chelsea faces an impossible job.

The Brazilian suffered a similar fate to Villas-Boas, lasting just a month less during his reign at the club which came to an end in February 2009.

"England has clubs like Arsenal, where Arsene Wenger has been for several years, yet has won only two or three championships," said Scolari, now in charge of Brazilian outfit Palmeiras, at a news conference.

"But Chelsea's culture is very 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."
