Villas-Boas says the challenge of consistently securing silverware is one he will relish.
He said: "The expectations are for the maximum. We want to win trophies, that is the challenge we face day by day in any business.
"Everyone wants to be the best and win something and the challenge is to win as soon as possible and to build a platform for the future.
"This is nothing different from any other club, the challenge in your everyday life is to be successful in what you do and that is the challenge I face here."
