Torres joined Chelsea in a record £50million deal in the January transfer window.
“Liverpool will always be very special to me,” Torres told Spanish radio station Cadena Ser. “Because of its history, Liverpool is a bigger club but it’s going through a difficult time.
“I thought I would stay one more year and take it as a transition season. But a time comes when you lose enthusiasm, you see those in the Spanish national team are playing at a different level.
“Then when everything looked black, Chelsea came and showed a real interest.”
