Villas-Boas, the former Porto and Chelsea manager, was recently appointed as Spurs' boss at the club's new £45 million training base in Enfield, but the 34-year-old Portuguese revealed his version of the story behind his sacking after eight months in-charge at Stamford Bridge.
"It was a tremendous learning experience which I am grateful in some ways to have gone through it because it makes me a better coach and a better person at this time," Villas-Boas said.
"But the decision to cut it short was not mine and for Chelsea to have won the Champions League and to have won the FA Cup was because we were still in those competitions."
"I respect the decision of the owner of Chelsea, but I will never accept it," the new Tottenham boss said.
Villas-Boas had signed a three-year contract with Chelsea after the Blues agreed to pay a release clause of £13.3 million to Porto.
"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 also who was not putting up to the things he promised."
"It was the putting together of different ideas towards the future. The fact that people quit on me, I have nothing to say any more."
Villas-Boas also had a disagreement with Chelsea veterans Frank Lampard and Ashley Cole. "I am not a guy who is able to criticise anyone in public, but I am not a guy who promotes individuals in public," he said.
After the sacking, Chelsea went onto win the FA Cup and their first ever Champions League title in history.
"For Chelsea to have won the Champions League and the FA Cup was because we were still in those competitions," Villas-Boas said.
"Whatever happened after I left was down to those players and Robbie for being able to turn it around. I have nothing to do with that success."
"But on the day of my dismissal, I told Roman that he could win these two trophies because the emotional impact when a manager goes is extremely strong, the players free themselves and the burden of pressure is taken off."
"I had the opportunity to win with them cut short and I had cut short the opportunity to qualify for the Champions League when I was just three points off the fourth position. And this is what I recall from the day when I was sacked," he said.
