At just 33, the Portuguese coach will be the youngest boss in the English top flight after he succeeded experienced Italian Carlo Ancelotti once the release from his contract with Porto had been agreed. Villas-Boas promised evolution not revolution after succeeding Ancelotti, who celebrated an historic league and FA Cup double in his first full season at the helm before being unceremoniously axed after a barren campaign. However, some changes behind the scenes are predicted, with long-serving first-team assistant coach Paul Clement set to leave, along with fitness coach Glen Driscoll and club doctor Bryan English. The Blues' opening pre-season friendly against Vitesse Arnhem in Holland on July 9 has been cancelled at the request of the new manager, who wants more preparation time with the squad. Villas-Boas is looking to bring in a new number two, after his preferred choice Vitor Pereira was appointed as his successor at Porto. Fitness coach Jose Mario Rocha and senior scout Daniel Sousa are, though, set to follow from the Dragons. Michael Emenalo, assistant first-team coach under Ancelotti, could take up a technical director role. The new Chelsea boss is also expected to be busy in the transfer market ahead of the new campaign, with Colombia striker Radamel Falcao and midfielder Joao Moutinho expected to follow him to Stamford Bridge from Porto. Villas-Boas - whose release from his Porto contract cost some 13.2million Euros (£11.8million) - is also likely to face questions over whether he was first choice for the position. Following Ancelotti's dismissal, it was widely reported former caretaker manager Guus Hiddink had emerged as the Blues' top target to reprise the role he enjoyed on a temporary basis following the departure of Luiz Felipe Scolari when guiding the Blues to FA Cup victory at Wembley in 2009. However, after Villas-Boas was confirmed, Chelsea maintained the Portuguese coach was the "outstanding candidate for the job" and there had been no formal approach to the Dutchman, who remains in his post with the Turkish Football Federation.
