Former Italy international midfielder Gennaro Gattuso has insisted that he has never been involved in any kind of match-fixing.
The 2006 World Cup winner's house was raided on Tuesday as part of an investigation into illegal betting in football.
"I am angry and offended," he told Mediaset. "I'm calm and I'm going to clarify everything.
"I do not want to have these marks on my career. I have never gambled in my life."
Former Napoli striker Claudio Bellucci and ex-Roma midfielder Davide Bombardini are also under investigation.
