Kallstrom is wary of the Reds despite the Premier League side’s injury problems and recent run of form.
“As a boy I watched Liverpool on TV and always admired them, many youngsters back then did,” he said.
“I suppose that to see them in their current position is a surprise, but it is not something that they cannot turn around.
“Things happen like this to even the greatest teams. There can be a few defeats, then a dip in confidence and one bad thing follows another.
“Everything seems to go wrong all at once. But they can recover from this.
“We know they have injuries, but it is not something we have been talking about.
“We have to plan for the match as if nothing of that sort had happened. They are still a great club with great players, and we must not forget that.”
Kallstrom added: “He (Torres) is probably the best in the world, I have played against him at international level and he is very clever with the ball and a very tough opponent.
“He is Liverpool’s best player and whatever injury he has, we must concentrate on stopping him and being clinical in our own play to get the result we need.”
