The Spaniard has struggled for goals since arriving from Liverpool and again drew a blank as Chelsea were held to a 1-1 draw at Swansea on Tuesday night.
With Didier Drogba away at the African Nations Cup there is even more pressure on Torres to get among the goals but none of it is coming from Villas-Boas.
"It is normal, he is taking his time," the Blues boss revealed.
"The confidence is there and we believe a lot in the player, he helped the team with his lay offs and passing and in this situation he has to continue to persist and maybe we can create opportunities that can help us win games.
"If we need to create more opportunities for him to score then that's what we need to do."
