Serie A has announced no action will be taken against Cagliari after Juventus midfielder Blaise Matuidi said he was the victim of racist abuse during his side's 1-0 win on Saturday.

The France international revealed in a post on his Facebook page that he "experienced racism during the match".

"Weak people try to intimidate with hate," he said.

Serie A says it cannot take any action because the referee and match observers did not hear the racial abuse.
