Dortmund sold Gotze to arch-rivals Bayern Munich but did not work towards securing a replacement ahead of the start of the summer transfer window.
Instead, the club have bolstered their defensive options as they have signed Werder Bremen defender Sokratis Papastathopoulos.
Riedle, who played for the likes of Liverpool and Lazio during his playing days, is not too concerned about the lack of activity on the transfer front as he told the Bundesliga website: "I have full faith in [head coach] Jürgen Klopp and [sporting director] Michael Zorc. I'm sure they won't panic and will find the right replacement."
"Klopp has a really good eye for a player's qualities and has pulled a number of lesser-known players out of the hat in the past. Neither Großkreuz, Götze nor Gündogan were necessarily expected to play a key role - and they really burst into the scene."
The 1990 World Cup winner did specify, though, that Gotze's ability to weigh in with the goals was an important attribute and therefore the recruitment process should seek to find similar individuals.
"To be honest, it isn't at all easy to replace a player of Mario Götze's qualities, as few in Europe are able to match him," he continued.
" If he's [Klopp] to actually replace Götze, then he has to be incredibly creative as well as a real goal-threat. It's not enough for him to get involved in the build-up; he also has to sneak in up front and score goals.
Furthermore, the 47-year-old believes that it will be important for the Bundesliga runner-ups to secure decent back-ups for forward Robert Lewandowski.
"Finding an auxiliary for Robert Lewandowski could be an option, as Julian Schieber couldn't match Lewandowski's performances last season, whereas it was a different story at Bayern, where Pizarro and Gomez served as great back-ups.
"I'm not worried at all about Borussia. The club has been doing everything right in the last years. BVB will continue on the right path."
