Chelsea striker Fernando Torres admits he has to do "much better" to justify his £50million price tag and retain the confidence of Roman Abramovich.
The Spaniard, currently on the sidelines with a knee injury, concedes that he needs to score more goals but he is confident that he will deliver if he is given time.
Torres scored 23 goals last season in all competitions, and has won the Champions League, Europa League and FA Cup in his time at Stamford Bridge.
He has scored 37 goals in 139 appearances in his Chelsea career so far but his move from Liverpool - where he scored an impressive 81 goals in 142 appearances - has not been the success most predicted so far.
"The people are looking at me thinking I should do much better and it's true," he 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," said the 29-year-old, who is currently sidelined with a knee injury.
"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."
Torres insists that despite his difficulties at Chelsea, he has no regrets about making the move from Merseyside.
"I'm so happy to have made that hard decision in my career to come to Chelsea," he said. "Over time you can see all the success that we've had as a team so everything was worth it."
And Torres believes that whilst improvements must be made, he believes the criticism directed at him has been over the top.
"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 (23) 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."
