The Spaniard only managed to score 11 goals in 49 appearances in his first full season at Stamford Bridge, however since moving to Chelsea he has won the Champions League, the Europa League and the FA Cup.
Currently sidelined with a knee injury, Torres has admitted that 37 goals in 139 appearances in a Chelsea shirt is not good enough, especially as he scored 81 goals in 142 appearances for Liverpool.
"The people are looking at me thinking I should do much better and it's true," the striker told Chelsea TV.
"The reason you pay that money for someone is that he has shown in the past he is worth that.
"Now what you have to show is you can have the same value or even more value for things you have done at Chelsea.
"I know I have many things to do at this club to give the confidence back to the owner. The amount of goals I scored last season should be the minimum.
"I want to ask that of myself but I have enough time. I signed a five-and-a-half year contract and I'm sure the future can only be better."
However, despite the fact Torres has failed to win over the majority of Blues fans, has had a rough time in the media and has been dropped from the Spanish national side in recent history, he has no regrets about moving to the London club.
"I'm so happy to have made that hard decision in my career to come to Chelsea," the 29-year-old said. "Over time you can see all the success that we've had as a team so everything was worth it."
Torres then went on to claim that an overreaction, mainly perhaps harsh criticism from the media, has made his form look a lot worse than it actually is.
"There has been an overreaction about everything. Overreact when I did a miss or if I have a red card or I hit the crossbar instead of scoring a goal.
"It was a good season [last year], a good number of goals  that gave us a chance to fight for trophies but if you ask the people, they will say he can do better, should do better.
"It's like I said, with me good things are looking so-so and bad things are looking really bad."
