Former Real Madrid coach Vanderlei Luxemburgo has been sentenced to 18 months in prison, but has the option to avoid jail time by paying a fine to the value of 100 minimum wages and carrying out community service.
The current Gremio trainer was running for office in his local electoral area and has been convicted of falsifying documents to change his district to Palmas.
Luxemburgo's agent, Marcelo Peixoto, spoke on behalf of his client, telling UOL: "He [Luxemburgo] has not been officially notified.
"Even without the content of the decision, we are convinced it will be overturned and that ultimately the truth will come out with no political interests."
Luxemburgo only took charge of Gremio in February this year after a two-year spell at Flamengo.
The 59-year-old's lawyers have promised to appeal the decision, which would also see him ineligible to run for political office for a period of eight years.
