He already looks more of a threat and followed up his goal against Manchester City in the Community Shield with another last night.
Cahill feels Torres will thrive now he has the responsibility of leading Chelsea's attack on a regular basis and told the London Evening Standard: "Maybe he will relish being the main man this season. He has done that at the start of the season and has been great for us.
"It is good to see him score so early in the season. He has dealt with pressure before and that won't be any different for him this time. He is the main man this year and has got off to a fantastic start. Fernando has worked hard in training like he always does. Even when he doesn't score he works hard for the side.
"To get off the mark already is great and he was scoring goals in the European Championships for Spain [where he won the Golden Boot] so he has taken that sort of form into this season."
