|11/2||Fernando Torres is 11/2 with Paddy Power to score the first goal against Atletico Madrid on Friday
The Spaniard played for Atletico for 12 years after joining the club at the age of 11, before leaving in 2007 to join Liverpool.
Torres admitted the affection he still feels for his boyhood club would stop him from celebrating if he were to find the net in Friday's game.
He told reporters: "If a goal is scored I will not celebrate it. It couldn't be more special. Their fans know I was one of them. I spent 12 years of my life there."
The 28-year-old feels he is finally back to his best after struggling for over a year with a lack of form following his £50 million move to Blues in January 2011.
Torres even believes he has become more of a team player since joining Chelsea, as he has contributed more assists than he has done in any stage of his career.
He added: "The only thing I know is I don't want to be in this situation again. I don't want to go back. I'm stronger than ever. I've become a better player since coming to Chelsea. I do more assists."
The Spain international has denied criticising his club after stating in May he wasn't pleased with the way he was being utilised.
He added: "I never said bad things about Chelsea. I know they made a big effort to buy me."
