Former-Arsenal manager George Graham insists his old side have nothing to fear when they face Fernando Torres on Saturday afternoon.
Torres has hit three goals so far this season, including a fine header in Chelsea's 6-0 midweek demolition of Wolves in the Capital One Cup.
But Graham believes the Spain international will not pose too much of a threat for the Gunners.
"You have to wonder what's happened to the Fernando Torres that was introduced at Liverpool?" Graham told Alan Brazil's talkSPORT show.
"He looked fantastic, was flying up either flank and making great runs. I just can't see him doing that again.
"Since he's gone to Chelsea he's not a hold-up player, he always wants the ball in channels."
Torres moved to Chelsea from Liverpool for £50m in January 2011, but has failed to live up to expectations at Stamford Bridge.
But this season has begun more positively for the Spaniard, and for Chelsea.
The Blues spent big this summer, bringing in Eden Hazard, Oscar, Victor Moses and Cesar Azpilicueta for more than £70m in total. And the investment seems to have paid off, with Hazard in particular settling quickly, and Chelsea are currently unbeaten atop the table.
Arsenal similarly endured a summer of transition, and have had to cope with the loss of star striker and last year's Premier League top scorer Robin Van Persie.
But Arsene Wenger's side have begun the season in fine form, and Saturday's crunch fixture pits two of the most in-form Premier League sides against each other.
