"I'm very well, happy with the progress of the injury," Torres told Marca. "Since January I've had two operations, and that isn't easy.
"Everything went very well with the first and in the second the objective was to be ready between six and seven weeks, and I'm at the start of the sixth.
"I will do a few more days of specific work and, God willing, I'll be 100% for the first game of the World Cup for sure."
If Torres returns to fitness in time for South Africa, he could be among the contenders to finish as top goalscorer in the tournament, with European champions Spain marked as potential winners.
But the forward is adamant he feels no added strain from being tipped as a possible leading scorer.
"No, but I know that, along with (David) Villa, I'm lucky enough to be one of the strikers in a team that are among the favourites, and that brings certain privileges," he added.
Torres admits that Spain adding the world title to their European success would allow him to end what has been a frustrating season at club level with Liverpool on a high note.
In addition to his injury problems, the Reds have failed to make an impact this term, finishing a disappointing seventh in the table.
"It's been a very difficult season. When you start a campaign you hope you will be able to fulfil your dreams, winning titles, not having injuries, enjoying yourselves, and it has been just the opposite," said Torres.
"But there is always a tomorrow in football and this summer, the World Cup.
"I've put aside the club, the bad season, and I want to finish in the best way possible way by making history with my country."
