Drogba's departure in the summer has meant Torres becoming Chelsea's first-choice striker, the 28-year-old starting almost every game this season.
He said: "I'm very happy about that because it's the role I like. Hopefully, it can be like this until the end of the season."
Torres has failed to score in the Premier League for almost two months, a drought that has co-incided almost exactly with Chelsea's seven-match winless run, their worst for 15 years.
Torres added: "We still have to improve other things as a team but I think we have the players. We just need more time.
"We have been very good defensively this season. But, in the middle, we have huge quality and those players have to be the key."
