Andre Villas-Boas has accused Chelsea owner Roman Abramovich of breaking promises to him.
The 34-year-old Portuguese, who took charge of London rivals Tottenham Hotspur last week, was sacked by the Blues in March.
He said: "I respect the decision of the owner of Chelsea but I will never accept it.
"I told him that for me it was him quitting on me when he had been so much involved in the beginning in bringing me in and he was the one who was not putting up to the things he promised.
"You have to understand, the decision to terminate what was going on at Chelsea was not mine, it was the owner's. It was the owner who decided to cut short the project."
Villas-Boas's Spurs face Chelsea at White Hart Lane on October 20.
