The Spaniard refused to apologise after being unveiled as interim boss yesterday.
Fans are furious that he taunted the club as Liverpool  chief but Benitez is convinced he can win them over.
"If I'm a fan, I'd want my manager fighting for my club. It wasn't a lack of respect for the Chelsea fans. It was a manager defending his team. I'm sure the fans here would like to see me doing the same," the Sun quoted Benitez, as saying.
"You can analyse every sentence I say. It's not the big issue. The big issue is that I was fighting, playing a top side in the Champions League semi-final," he added.
At the time of that 2007 clash, Benitez said: "Chelsea is a big club with fantastic players. But I would never take that job. For me there is only club in England, Liverpool."
But owner Roman Abramovich did not care and Benitez's first game is against Manchester City on Sunday.
Benitez insists the Blues can win trophies over the final seven months of the season.
"I saw today a lot of players with a great attitude. Torres was one. Can we help them improve? It will be easier with Fernando. He is a top-class player and with his attitude, he'll do it. I know how good he can be," Benitez said. (ANI )
