The 68-year-old, who was a key player for his country between 1965 and 1975, believes the Spaniard is going to have a huge effect on Germany's top league next season and beyond.
"It's a massive piece of good fortune for the Bundesliga that a coach like Guardiola will soon be arriving," Netzer told Fifa.com.
"He won't only have a huge say in the direction of Bayern but of the entire league. I'm sure of that.
"I think we need some new ideas and some new impetus in Germany, and that can only come through foreign coaches that favour a different style of play and have a different footballing philosophy.
"Obviously, not every team is going to be able to play football in the image of Guardiola, but he will definitely provide a fresh impetus to the league."
Despite Bayern's historic treble-winning campaign last season, Netzer still feels there are areas to improve within the side on which Guardiola can focus.
"I'm sure he will continue to develop them and I'm very intrigued to see how he does it," he said.
"There's definitely the potential to improve them, otherwise Bayern wouldn't have hired him. That's not to say that he will sacrifice any of the good things that the team has done this season though."
Guardiola signed a three-year deal with the German giants in January.
