Joachim Low's side have been functional rather than flamboyant in the tournament but impressed as they saw off France in the quarter-finals to set up a last four clash with Brazil.
Germany have often adopted a striker-less system, with attacking midfielder Thomas Muller leading the line and their only out-and-out goalscorer, 36-year-old Miroslav Klose, operating as an impact substitute.
And while Raul has applauded the efficient manner in which the Germans have made their way through the tournament, the Spaniard feels they are limited in attack.
"There was a warning in that performance (against France), as for the first time in the tournament they demonstrated their ruthlessly efficient side, with the midfielders taking control early and not letting it slip," he said in his column for Times of India.
"But what I miss in this German squad is a poacher like Jurgen Klinsmann or Rudi Voller in the box. We grew up watching them.
"Klose is among the World Cup greats and one has to respect a striker who, with 15 goals, is the competition's joint-highest scorer of all-time. But he is 36 and it's unfair to expect from him now what he did in the past."
Semi-final opponents Brazil face their own attacking dilemma following the tournament-ending injury suffered by Neymar, and Raul noted the pressure on the shoulders of Hulk and Fred to deliver goals.
"Scolari's team has other headaches as well," he added. "Fred and Hulk are not firing and even with Neymar on the field, they had to depend on the stoppers for goals in the last two games.
"I expect Dante to partner David Luiz because the Bayern Munich defender will have an idea of how to stop four of his club mates."
"It won't be easy because the Germans are masters at sniffing weaknesses. Brazil will have to hold shape and be on their toes all the time. Very few get the chance to beat them on such a stage. This is the time for Germany to rewrite history."
