Volpato was pulled over by police on Sydney's Anzac Bridge on July 24 after driving at 109km/h in a 60km/h zone. He initially returned a positive roadside reading for cocaine, but a private clinic test claimed he returned a negative result. However, a secondary oral fluid test by police again confirmed a positive result for cocaine. Volpato's club side, Sassuolo, has stated that he undertook a test when he returned to Italy, which was negative.
ESPN Soccer reports that Volpato's immediate availability for the Socceroos rests in the hands of Football Australia, which is currently seeking independent verification of the test result. The matter is being managed in accordance with Football Australia's established protocols, but the positive reading on Volpato's secondary police test could have major ramifications for his availability heading into January's AFC Asian Cup.
