Villas-Boas claimed billionaire owner Abramovich would not have paid a world record £13million to prise him from Porto this summer, only to sack him at the first sign of trouble.
He said: "It's not a question of the owner having patience.
"We have set out to build something new at this club and the club is committed to taking what we're building to the future.
"The owner didn't pay 15million euros to get me out of Porto to pay me another fortune to get out.
"Our commitment is towards the club and what we are doing in the future.
"We have enough talent to compete in all competitions, and that's the perspective we take at the moment."
