The Spain international joined Andre Villas Boas’ men back in January for £50 million, but has received criticism as he has only scored five goals in 30 games since signing.
Despite not playing to his potential during his time at The Blues, Torres feels he has the ability to get back to his best.
“Whenever you go somewhere new, you expect to have difficulties,” he told Mirror Football.
“But whenever I have had difficult times, I look at myself and say, ‘Yes, I can get back to my level.’
“All that I need to do, above anything else, is to work. If you work and give everything and really want to do something, that is all you can be asked.
“If you do that and things do not work out, you have nothing to be ashamed of.
“But I am in debt to the Chelsea fans. They have always supported me. And I promise them the one thing I have never done and will never do in my life is give up,” he concluded.
Torres will most likely feature for Chelsea against former club Liverpool in a mouth-watering clash at Stamford Bridge on Sunday.
