Rino Gattuso, the former AC Milan midfielder, is under investigation for alleged match-fixing in Italy.
Prosecutors claim Gattuso and his one-time Milan teammate, Cristian Brocchi, are allegedly part of a ring that fixed Serie A matches at the end of the 2010-2011 season.
La Gazzetta dello Sport report both players' houses were searched on Monday night during raids on 15 houses in northern Italy, as part of the ongoing Calcioscommese investigation.
The news comes after recent events in England regarding spot-fixing. Six men, including footballers Sam Sodje and DJ Campbell, were arrested following accusations a player rigged a Championship game for cash.
Four men, Salvatore Spadaro, Francesco Bazzani, Cosimo Rinci and Fabio Quadri, were arrested.
Gattuso, 35, won the Champions League twice with Milan and started all but one of Italy's matches during their 2006 World Cup-winning campaign in Germany.
He ended his playing career this year and was named Palermo manager in June, but was sacked after only three months.
Italian football has previously been blighted by the Totonero and Calciopoli scandals in 1980 and 2006.
Last year, Juve coach Antonio Conte was banned for three months and fined €200,000 after it emerged he had knowledge of an attempt to fix Siena matches against Novara and Albinoleffe, but failed to report them.
