( CNN ) -- Chelsea 's sacking of Andre Villas-Boas came under fire Monday with former Blues boss Luis Felipe Scolari warning it will be `` hell '' for whoever succeeds the Portuguese at Stamford Bridge . Ex-Brazil national team boss Scolari is one of six managers dismissed by Chelsea owner Roman Abramovich and , like himself , does not believe Villas-Boas was given enough time by the Russian billionaire . `` England has clubs like Arsenal , where Arsene Wenger has been for several years , yet has won only two or three championships , '' he told a news conference for his present club Palmeiras . `` 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 .

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 . '' Blog : Can English clubs catch Europe 's best ? But Dutch legend Ruud Gullit , who managed Chelsea before Abramovich took control , told CNN that he disagreed with Scolari . `` I do not think it is 'hell ' -- I had a great time at Chelsea which I still treasure , for me it was no hell . '' Gullit hinted that he believed Villas-Boas needed to have made better use of his senior squad members . `` The older players need to help the younger players know how to play the game , you ca n't ignore them by putting them on the bench and not in the team . '' Richard Bevan , the chief executive of the league managers ' association , also condemned the sacking Monday . `` Looking for what is an eighth manager in nine years is a serious embarrassment to the owner , the club , the fans and the league , '' Bevan told BBC . Bevan had spoken to Villas-Boas , who was `` very disappointed , frustrated ( and ) saddened '' by his dismissal . And Arsenal manager Wenger also believed that Abramovich had been hasty to remove Villas-Boas . `` I feel sorry for him and it 's sad every time a manager loses his job because it 's a job that demands a full commitment and I think he did that . `` I am sorry he was not given enough time to do his job , '' he told gathered reporters . Chelsea players have also come out in support of their former manager with central defender David Luiz thanking the Portuguese . He said on Twitter : `` Thanks AVB ! You are an amazing guy ! Big hug . '' Midfielder Juan Mata , one of Villas-Boas ' signings , also reacted on Facebook . `` It has n't been an easy day for those who , like me , are part of Chelsea . I would like to thank the manager and wish him luck . `` We have to keep working hard and better days will come . Thanks for your support ! '' Chelsea made a move to strengthen its coaching staff Monday after the departure of Villas-Boas by appointing former player Eddie Newton to assist interim manager Roberto Di Matteo . The 40-year-old Newton was assistant to Di Matteo at both MK Dons and West Bromwich Albion , but told Sky Sports his appointment had come `` totally out of the blue . '' Di Matteo later told Chelsea TV that the club `` have to move on '' after the sacking of Villas-Boas . `` Andre has brought some very good , positive ideas and changes to this football club and we will benefit from his changes , '' he claimed . `` Our duty now is to look forward and to try to get the results that we need in the league , the Champions League and in the FA Cup to have a good season . '' The first test of the new management team will be an FA Cup replay on Tuesday night at second flight Birmingham .
