Bayern Munich President Uli Hoeness goes on trial Monday over a tax evasion case that could land the German soccer icon in prison.
Bavarian prosecutors filed charges against Hoeness last year after he reported himself to authorities for having a previously undeclared Swiss bank account.
Munich daily Sueddeutsche Zeitung, citing the still-secret indictment, reported last month that prosecutors believe Hoeness dodged paying up to $4.9 million in taxes.
The Munich court will have to decide whether the 62-year-old's amended tax return entitles him to be let off with a fine and possibly a suspended sentence.
Otherwise the Bayern boss, who was part of Germany's 1974 World Cup-winning squad, could face up to 10 years in jail.
A verdict is expected by the end of the week.
