More than one Blues star has been linked with nouveau riche PSG in recent days, especially after it emerged Ancelotti would be their new manager. The former Chelsea boss was finally unveiled on Friday afternoon and is expected to be given a huge transfer war chest by the French club's billionaire Qatari owners when the window opens on Sunday.
But any approach for one or more of the players Ancelotti managed for two years at Stamford Bridge would be rebuffed, according to Villas-Boas, who said: "They're not for sale. It's a situation that can happen."
Villas-Boas himself failed to land Porto wing-back Alvaro Pereira after leaving the Portuguese champions for Chelsea this summer, while he has also been linked with Joao Moutinho and Hulk.
He added: "There's always that possibility because you get to know people from the past."
Didier Drogba, Florent Malouda, Salomon Kalou and even Frank Lampard have been linked with January moves away from Chelsea, who are looking to offload Alex and have already allowed Nicolas Anelka to join Shanghai Shenhua.
Villas-Boas refused to rule out further January sales but insisted the Blues had "no interest" in letting anyone else leave.
Malouda this week publicly admitted he would be prepared to move on in search of regular first-team football, while fellow forward Kalou is seeking assurances of more game time before signing a new contract to replace the one that expires this summer.
Drogba, who is also a free agent at the end of the season, has already rejected a one-year extension to his Blues deal and he and Kalou are less than two days away from being able to pen a pre-contract agreement with a rival club.
