Villas-Boas comes to the club after the departure of Carlo Ancelotti, for whom two trophies in his maiden season were not enough to save him from the axe after a barren 2010/11 campaign.
As such, the new manager is aware of the expectations which will surround him in west London and is ready to meet them.
"Chelsea is a club that in the last six years has achieved so much and people are expecting us to be the same way," he said.
"There is not going to be more or less tolerance for me if I am not successful so this is the challenge I face and I feel confident that we can motivate everybody, not only the players but also the structure.
"I feel confident I can respond to the ambitions of the supporters and the ambitions of the owner and the administration."
