"It was a great result coming after the game against Chelsea," Torres told Sky Sports. "The last game wasn't good, but we've done our job.
"We have confidence after this result to go to Stamford Bridge on Tuesday."
Torres' first goal was a contender for goal of the season, as he controlled a long ball on his chest before swivelling to hook a fierce strike into the far corner.
"Sometimes you try to score like this, but normally the ball goes out," he added. "But this one went in. It was a good goal."
