The Euro 2012 golden boot winner has endured a torrid time since his £50m move from Liverpool in January 2011, having gone on a number of goal droughts.
However, the 28-year-old found the net in the 2-1 win over Arsenal on Saturday to register his fifth goal in all competitions this season.
"I am enjoying it more this season with the kind of players I have in the middle behind me," he told the club's website.
"It is giving me a lot of support and I hope to improve, trying to create more chances for the team. I don't shoot on goal too much but even with this I am scoring goals so the team is going to improve - not just me, everyone.
"With this different style of football we are playing this season we are at the top of the league and we can dream of a very good season again. I had a very difficult beginning at Chelsea but that is in the past now, and I am enjoying the present with a great group of players and we are building a big team."
Torres scored just 12 goals in 67 games for Chelsea prior to the beginning of the current campaign.
