The German Football League (DFL) president Reinhard Rauball has said that only a re-founding of FIFA can end its crisis.
His comments come days after a criminal investigation was opened into FIFA president Sepp Blatter, with FIFA having been embroiled in a corruption scandal that erupted earlier this year.
"It's about time to consider a plan B," Rauball told German newspaper Suddeutsche Zeitung. "The U.S. justice department has classified FIFA as influenced by organised crime and corruption."
Rauball said Blatter needed to resign immediately, and that the ongoing situation could force world football into a restructuring process.
He said he hoped that could lead to a new structure similar to "a German stock company with a professional executive and a board of directors" and including people from outside football.
Rauball, who is also a vice-president of the German FA (DFB), has been spoken of as a potential replacement at the top of German football if current boss Wolfgang Niersbach takes over the UEFA presidency from Michel Platini.
Platini is being treated as "between a witness and an accused person," according to Swiss attorney general Michael Lauber, over a payment of two million Swiss francs made to him by FIFA in 2011.
The money was paid to him nine years after the work it was said to be for had been completed, and Rauball said the former France star needed to offer "a credible explanation."
"What Platini has told us so far is just not enough," he said.
In response to questions about the payment, UEFA said on Wednesday: "The president has been fully open and transparent with the authorities. He has not been accused of any wrongdoing."
