The Spaniard has struggled to impress at Stamford Bridge following his £50m move from Liverpool in January 2011.
However, the 29-year-old believes that he can still improve as he looks to see out at least the final three years of his current contract with the Blues.
"I have many things still to give to this club," he told reporters. "I have three more years [on my contract] so I'm expecting to stay at least three years."
Torres has scored 20 goals in all competitions for Chelsea so far this season.
