Torres insists there are reasons behind the move that have yet to be made public and also heaped praise on former Liverpool manager Rafael Benitez.
"Liverpool's fans have stuck with the story the club gave and they don't know the real story," he told the Spanish newspaper Marca.
"I don't feel bitter towards them, they will always be special for me.
"I owe so much to Rafa Benitez, no one understood me like him.
"He's a great coach. His teams go out with just one thing in mind: compete.
"Even with a smaller budget his teams can compete with the best."
