Andre Villas-Boas hit back at Roman Abramovich, accusing the Billionaire Chelsea owner of "quitting on me."

Villas-Boas, who is now the new Tottenham Hotspur manager, had an unsuccessful and tumultuous 9 months with Chelsea after taking over the Stamford Bridge club at the beginning of last season. His views and playing style were opposed by several senior players in the Chelsea camp, which led to his eventual downfall, despite the heavy backing of Abramovich at the beginning of last season.

In his first press conference with the media to reveal Spurs' new state-of-the-art training center, Villas-Boas said, while he respected the decision to let him go, he would never accept it.

"I respect the decision of the owner of Chelsea but I will never accept it," the Portuguese said.

"I told him that for me, it was him quitting on me when he had been so much involved at the beginning in bringing me in (from FC Porto) and he was also who was not putting up to the things that he promised.

"What reason did he give to me? I'm not sure if I can make it public but the reasons don't go along or can't be applied to the fact that I was dismissed."

Villas-Boas felt the decision to let him go was taken too quickly, even though Chelsea went on to win the FA Cup and Champions League after Villas-Boas' assistant Roberto di Matteo took over.

"The decision to terminate what was going on at Chelsea was not mine, it was the owner's," the 34-year-old said.

"It is all very well that you cut the project short and Chelsea go on to win two trophies and say how wonderful the squad was, but at the beginning nobody believed in that squad when we put it together.

"It was a tremendous learning experience, which I am grateful in some ways to have gone through because it makes me a better coach and a better person at this time.

"But the decision to cut it short was not mine and for Chelsea to have won the Champions League and the Cup was because we were still in those competitions. I had the opportunity to win 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.

"This is what I recall from the day when I was fired.

"I am always a person who defends certain principles that were never understood in England and it requires much more adaptability from myself.

"I am a person who always puts the team in front and I do it publicly. I'm not a guy who is able to criticise anyone in public but I am not a guy who promotes individuals in public. I understand now that certain things can be done better and you evolve in different ways. Hopefully, I can apply the different things I have learned properly."

Villas-Boas, however, admitted the appointment of a new manager had galvanized some of the veterans, which in turn helped the Blues to secure considerable success at the end of the season.

"On the day of my dismissal, I told Roman that eventually, you can win these two trophies because the emotional impact is extremely strong," he said.

"I was able to benefit from it when I went to Académica and they were rock bottom. Players free themselves; a burden of pressure is taken off them.

"That is exactly what happened at Chelsea. I don't see what they achieved as part of what I left there. What I had to do is put that squad together to be able to play those finals and to win them."
