Torres says there his options were limited when deciding to leave Anfield.
He said: "This club and this city offer me all I need to achieve my dream. When I left Spain for Liverpool I thought it was the definitive move in my life but that turned out not to be the case. I've maybe got five and a half more top-class years in my career and you have to do everything in your power to achieve your dreams, which is why Chelsea is ideal.
"I wouldn't have joined Manchester United out of respect for the Liverpool fans, I wouldn't sign for Real Madrid because of my support for Atlético. Barcelona don't need my type of player and Italy doesn't attract me, which meant it had to be Chelsea.
"They were the only ones where I could go and also improve myself. I'd started to take the decision to leave when the stream of sales started with Crouch and Arbeloa then Xabi Alonso and Javier Mascherano were all sold."
