Andre Villas-Boas in trophy pledge at Chelsea

NEW Chelsea manager Andre Villas-Boas believes he can satisfy the club's thirst for silverware and accepts he will be held to the highest of standards at Stamford Bridge.

The 33-year-old, who worked in Jose Mourinho's backroom team during his time at the club, was yesterday confirmed as Carlo Ancelotti's successor on a three-year deal that will see Chelsea pay Porto a release fee of around 13.3?million.

With a domestic double and the Europa League to his name in just one season in charge of Porto, Villas-Boas is confident he can deliver the desired results.

"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," he said.
