The Blues ended with Champions League qualifications and as Europa League winners.
Torres hopes to carry momentum through to the start of the new season.
He said: "Our expectations were high (last year) because we won the Champions League and we were fighting for many trophies at the beginning of the season.
"Everything was difficult at Christmastime - we changed the manager and we lost the chance to win a couple of trophies.
"It was not easy but the team showed character and the level we should have had for the season by winning the Europa League and finishing in the top three.
"You cannot say it is a bad season. We have had a good season, won a European trophy and hopefully the new season can be better."
