Reflecting on his Euros success with Spain, Torres said: "It was a great experience and the first big honour I've won. Now I know how it feels to win something like that, it makes me even hungrier to win trophies with Liverpool.
"I came here for that reason and hope this season will be better than last year.
"I believe we can win the Premier League or the Champions League. If we did that, it would be fantastic. We have started well, so there is optimism.
"But I'd be happy with just 20 goals if we won the Premier League or Champions League."
