The Blues will attempt to bring in another forward in the January transfer window to provide both cover and competition for Torres, who is finally showing signs of justifying his £50million price tag.
It has taken the 28-year-old nearly two years and an almost uninterrupted run in the side to get to this point, having spent the first 18 months of his Stamford Bridge career languishing in the shadow of Didier Drogba.
Torres admitted earlier this season he would not want to go through that again, meaning he could be forgiven for opposing anything that would risk a repeat.
But interim manager Benitez claimed that far from being against Chelsea reinforcing their attack next month, Torres was all for it.
"He knows that we need this competition, we know that we need this competition," Benitez said.
"The problem in January always is, 'Which one?'. Which player is available, which player is good enough to be here in a top side?
"So, it's not easy, but I think it will be positive for everyone.
"And Fernando is ready to fight for his position. He has no problem because he has a lot of confidence and he is enjoying now his football."
Indeed, Torres has six goals in his last five games, by far his most productive spell since his move from Liverpool.
It is no coincidence that his revival began within a fortnight of the appointment of the man who helped him become one of the best strikers in the world.
Former Anfield boss Benitez lifted the lid on the changes he had made to Torres's game, admitting his fellow Spaniard had not been helping himself by dropping too deep.
"I was watching games before I was here and he was trying hard," Benitez said.
"Now, he's trying hard maybe in the right positions."
Benitez admitted last month that he did not know whether Torres would ever recapture his Liverpool form but he said on Friday: "He's getting closer. That's very clear."
Torres is Chelsea's most used outfield player this season and Benitez described him as "clever" for recognising he would eventually need a breather.
But he added, jokingly: "I have to talk with [Lionel] Messi and check how he is doing because he's playing every game and scoring goals every time.
"Physically, he [Torres] is improving, he has more confidence, scoring goals and then he can carry on. How long? We will see."
Speculation is rife over who Chelsea will try to sign in January.
Atletico Madrid's Radamel Falcao is the marquee name but there are doubts from both parties' point of view over whether a deal will be done next month.
Chelsea's Champions League exit could make them unwilling to splash a Torres-like fee on a player.
"What I know for sure is that the club will try to do the best for the team," said Benitez, who was confident big names would not be put off joining the Blues because of their slide into the Europa League.
"The Champions League is a massive competition but still you have a lot of competitions to play for.
"Good players, the top-class players, they are looking for a good club, not just for one year, for the rest of the seasons of their contract."
Benitez was also determined for his current crop of players to take the Europa League just as seriously.
"It doesn't matter what the name of the other team is," he said.
"We have the Europa League and some people will say, 'You are in the Europa League and we are in the Champions League'.
"Yes, but you have to win the competition that you are in.
"For us, it's the same in terms of preparation of the team. It has to be exactly the same."
Last season, Chelsea's players watched their Champions League quarter-final draw live on television but there was no repeat for the Europa League last 32.
This time, the draw clashed with a training session although Benitez himself had little interest anyway.
"I don't waste too much time with this," he said.
"It does not change anything to watch the draw on TV."
