Lawyers representing Lazio and Milan in Italy’s football corruption tribunal say the clubs have no case to answer.
The pair, along with Fiorentina and Juventus, face relegation, points deductions and fines if found guilty of sporting fraud.
“We at Lazio are innocent. We don’t have anything to admit,” said lawyer Gian Michele Gentile.
Juventus’ lawyer Cesare Zaccone has already said his clients could settle for relegation and points deduction as “an acceptable punishment.”
The scandal emerged following the publication of transcripts of telephone conversations between former Juventus general manager Luciano Moggi and Italian Football Association officials, discussing refereeing appointments in the 2004-05 season.
The Rome tribunal in Rome is investigating claims that the clubs tried to influence the outcome of matches by interfering with the appointment of referees.
It is due to deliver its judgement on Monday, the day after Italy play in the World Cup final.
Lawyer Marco De Luca, representing Adriano Galliani, the vice-president of Milan, also claimed his client had done nothing wrong.
“Respect for the rules is in Milan’s DNA,” he said.
