Former Israel coach Grant was sacked by the Blues's hierarchy last summer, despite leading the club to the finals of both the Carling Cup and Champions League and a second-placed finish in the Premier League.
And although World Cup winner Scolari making a swashbuckling start to life at Stamford Bridge, thrashing Portsmouth 4-0 on the opening day of the season, both results and performances steadily diminished leading to the Brazilian's sacking after just seven months at the helm.
Cudicini, who continued to play second fiddle to Czech No.1 Petr Cech following Scolari's arrival, feels the former Portugal national coach struggled to adapt to the day-to-day running of club management in the hustle and bustle of the Premier League.
"It just didn't work out," the told the Sunday Times. "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 far too long. 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. Jose [Mourinho] 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."
