Former Italy striker Giuseppe Signori was among 16 people arrested for match-fixing in a co-ordinated sting by Italian police on Wednesday. Amongst those targeted were ex Serie A players and current players from both Serie B and Serie C as well as club directors from the lower leagues, all suspected of being part of an organisation that rigged games to fix bets. Eighteen matches are under investigation including this season’s Serie A encounter between Inter Milan and Lecce. Matches involving Siena and Atalanta, who both earned promotion to Serie A, are also under the microscope. Atalanta’s veteran captain Cristiano Doni has been named in the investigation but the club has made no comment on the affair. Doni is alleged to have collaborated with the organisation to ensure at least three goals were scored in his club’s match against Piacenza on March 19, it ended 3-0 to Atalanta. The investigation was led by the mobile squad from Cremona but also included help from police forces from a dozen other towns, including Rome, Naples and Turin. .
