Chelsea striker Fernando Torres has admitted that he needs to perform better this season to justify his £50m transfer fee.

The Spaniard, who scored 23 goals in all competitions last season, said that he is confident he can continue to improve under manager Jose Mourinho.

"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.

"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 went on to say that he has no regrets about leaving Liverpool for Chelsea, insisting that he is "so happy" at Stamford Bridge.
