Reports have suggested the Stamford Bridge club are prepared to listen to offers in the region of £20m for a striker who they only signed from Liverpool in January 2011.
But Villas-Boas, who took over at Chelsea this summer, has remained adamant the Spain international is not for sale at any price.
Torres has scored just five goals at club level since his unsavoury Liverpool exit almost 12 months ago and has recently fallen behind Didier Drogba in Villas-Boas’ plans.
The ex-Atletico Madrid star has started only 11 matches this season and was an unused substitute in Monday’s Premier League victory over Manchester City.
But Villas-Boas said at a press conference on Thursday ahead of Saturday’s trip to Wigan: “Fernando Torres is not for sale at any price, now or in the summer.”
Speculation has also suggested Frank Lampard, 33, will be sold either in January or at the end of season and the England international has been linked with LA Galaxy.
Villas-Boas is thought to want to reduce the age of his squad and has over the past month been preferring the central midfield partnership of summer signings Raul Meireles and Oriol Romeu.
But Lampard came off the bench to score the winning penalty in the victory over City and his manager, who is just eight months older, has offered an endorsement of Chelsea’s 2001 signing from West Ham.
“Frank Lampard is a player of massive magnitude to this club,” said Villas-Boas.
Lampard revealed after the win over City he had not held talks with Villas-Boas to discuss why he has been demoted to a role as a substitute.
And having previously in December accused the media of a premeditated agenda against his club, Villas-Boas has now said: “I haven’t followed Lamps’ comments after the game.
“I know that the headline played like that, which is fair because in the end it came out of his mouth.
“What I would say is there are plenty of players that push for starting XI selection and Frank is not the only one.
“There are people that are making great efforts to get into this Chelsea squad. Lamps’ is, I think, one of the top-five players most used.
“Every player wants to be involved in every game. But sometimes it is just not possible.”
