Torres has gone 1,074 minutes without a goal for Chelsea after he again failed to hit the back of the net in his side's 1-1 draw at Swansea City on Tuesday night.
The Spain international has now scored just three goals in 32 Premier League appearances since signing at Stamford Bridge from Liverpool for £50 million in January 2011.
When asked about his attacking options, Villas-Boas chose to talk up Didier Drogba's quality, with the Ivorian due to return from African Nations Cup duty this month.
The Portuguese said in The Sun: "The two players are competing for the striking position and we all know the significance of Didier to this team and his record.
"We will have to see how tired he is when he comes back to us but no one can doubt his ambition to win trophies for us this season. With Torres, the situation does not change. We still believe in the player but he is taking his time."
