Luiz Felipe Scolari is preparing to lead host nation Brazil at the World Cup, but he may have other things to worry about as he could face criminal charges in Portugal.
The 65-year-old coached the Portuguese national team from 2003 to 2008 and it appears that he is being accused of an offence during that period probably relation to avoiding tax.
Associated Press have reported that the attorney general's office in Portugal has confirmed that a criminal investigation has been launched with Scolari involved, but have given no further details.
Reports in the Italian press, which have been backed up in Portugal's media, suggest that Scolari is being accused of not declaring payments made for revenue from image rights and instead transferred the money to accounts in Miami.
The sums of money are not completely clear but it has been suggested by the Brazilian media that it could be around £6m that was kept away from the taxman.
The money reportedly flowed from Chaterella Investors Limited to a bank account in Miami with Credit Lionnays.
Scolari has spoken out in his defence, insisting that he hasn't knowingly done anything wrong.
"I have always declared my earnings in any country I have worked in," he is quoted as saying.
"I know that I am in the right. If something is wrong it isn't my fault. I hope that the powers of justice get to the bottom of the facts."
The news comes as a blow to Scolari's concentration just days after he announced his Brazil squad for the World Cup.
