Spaniard believes winning the European Cup would be "one of the greatest moments" of his life and insists he has nothing to prove against Barcelona.
"I know the ambitions this club have in terms of winning the Champions League, but it's the same as what I have myself,” Torres told the club's official website.

“It's something I dreamed about as a youngster growing up.
“I never really thought about winning the World Cup as I thought it was impossible. But now I have achieved that and I know what it feels like, so to win the Champions League would be a dream come true.
“It was the only trophy I wanted as a kid, to hold it in my arms. If we do manage to win it, I'm sure it will be one of the greatest moments of my life.”
Despite a rocky season at Stamford Bridge, Torres says he is delighted with the position the club is in at the moment.
“There isn't one single club in the world that can guarantee trophies, but top teams like Chelsea are always fighting for them, so now it's time to be patient, build a great team and it's good for me to be involved with such a good side, like the one we have now," he explained. “There's still one month left in the season, we're in the final of the FA Cup, the semifinals of the Champions League and this is what I want.
“Whether you win or not, that is down to football, but we are there and that's the main thing.”
The Spaniard has an impressive record against Chelsea's semifinal opponent.
During his six years in the Atletico Madrid senior team, Torres scored seven times in 10 games against the Catalan giants and he is looking forward to the game.
“I have a good record against Barcelona,” he added. “They are the type of team you have to defend well against and play on the counterattack, which is the type of game I enjoy. When I was at Atletico Madrid, we won at the Camp Nou two or three times.
