FIGC President Giancarlo Abete insists Italian football is clean.

Serie A, B and Lega Pro games were highlighted due to unusual betting patterns, which prompted an investigation into possible match-fixing.

"It's not an issue of acting harshly to set an example, but rather to ensure the rules are respected," said the Federation chief.

"The games under investigation are not very important, but highlight a new concept of match-fixing that is no longer tied to the result as much as making certain individuals richer.

"We must also have the ability to see the glass half-full. Italian football is primarily clean and does not need to be revolutionised by a few individuals in this scandal.

"Having said that, we will increase the penalties for those who do not report attempted corruption."
