The former Blues keeper told the Sunday Times: “It just didn’t work out. I didn’t say he was the wrong man the day he was appointed because I didn’t know him then but now I know he was a mistake. He had been an international coach, not a club manager, for too long. He wasn’t used to the daily involvement with players and the daily training and organisation of things.
“It was a different culture for him, too. English football is totally different to what he knew and he found it difficult to adapt to the style and speed of the game. He was a very nice guy but not the right person.”
Contrasting Scolari with Jose Mourinho, who won two Premier League titles with Chelsea, Cudicini said: “Jose adapted very well to English football straight-away. As soon as he arrived he seemed to know the players and what was required - the mentality, the way to train, everything.
"Scolari just didn’t have the same impact.”
