The trial of four leading Italian football clubs on match-fixing charges has begun in Rome.
The Italian Football Federation (FIGC) has charged four clubs and 26 individuals with fraud and match-fixing.
13 players from the four clubs in question are currently playing for Italy at the World Cup finals in Germany.
Juventus, champions for the past two years, is one of four clubs accused of running a system that would fix not just matches but the entire Serie A Championship.
A report commissioned by the FIGC accuses the former Director of Juventus, Luciano Moggi, of arranging referees for certain domestic and European fixtures.
Mr Moggi has already resigned, as has AC Milan Vice President Adriano Galliani.
Fiorentina, AC Milan and Lazio will also appear before the tribunal, which is taking place at Rome's Olympic Stadium. If found guilty, the clubs could be relegated and fined.
Reports say Juventus could be relegated to the Third Division and have to hand back the two trophies won this year and last year.
The prosecution case rests largely on phone taps.
One conversation allegedly refers to match official, Roberto Rossetti, who refereed the Spain-France game on Tuesday.
Tribunal President Cesare Ruperto opened the trial with a roll call of the accused who stood up as their names were read. Those appearing have denied the charges.
The trial, which was beamed by closed circuit television to media gathered in a nearby room, quickly moved to procedural issues that dominated the morning.
The panel consists of five retired judges and one representative from Italy's referees association.
