When asked if Torres was more of a bargain than Berbatov or Manchester City's British record £32.5m buy Robinho, Benitez said: "He was a good signing.
"He was a big price but we knew we were signing a young player who could improve. His value is higher now. He was a good signing in every sense.
"I would not want to swap Fernando with anyone else in the world because he is my player and I'm very pleased with him.
"There are good players in Europe and all the way around the world, but better than Torres - no.''
