Only Steven Gerrard, who is being rested, and Daniel Agger, who has had an MRI scan on a groin problem which has not responded to treatment, missed the trip.
But Hodgson said it should not be assumed Torres would automatically take his place up front but revealed he had learned a harsh lesson after the Carling Cup exit to League Two side Northampton.
A week ago the Reds boss gave his first-choice side the night off but then saw a second-string lose on penalties.
Hodgson admitted that, in hindsight, it would have been worth having some quality players in reserve - hence the presence of Torres and most of the first team.
"The mere fact he is here does not mean he will be in the starting XI," said the 62-year-old.
"When you are playing against Northampton and it is 1-1 and you are not playing very well you are desperate to change the game.
"You look around you and realise you have given all the quality players time off to prepare for the game on Saturday and you would like desperately to bring on maybe one of those players - that is one of the things that has affected my thinking."
