Socceroos young gun Cristian Volpato is in hot water after allegedly testing positive for cocaine on Friday.

The midfielder made waves at the World Cup following his late defection back to his birth country from Italy.

But his immediate future is now uncertain after he was stopped by police twice on Thursday night and the early hours of Friday morning.

Driving a BMW, Volpato was allegedly clocked at 109km/h — nearly 50km/h over the designated speed limit — on Sydney’s Anzac Bridge at 1.10am on Friday.

He was stopped one street over and subjected to a roadside drug test which allegedly returned a positive result for cocaine, police said in a statement on Friday.

A secondary sample of oral fluid was taken for further analysis.

He was issued another fine and his international driver’s licence was suspended for six months.

Volpato had earlier been stopped at 11.05pm on Thursday, police said, for travelling between 86 and 94km/h in a 60km/h zone. He was given a fine.

He returned a negative result when he was given the initial roadside breath test.

The 22-year-old plays for Sassuolo in Italy’s Serie A.

Volpato visited local clubs around Sydney since returning from the World Cup but was due to return to Italy for pre-season training in the coming days.

Long set to become one that got away from the Socceroos as he publicly hoped for an Italy call-up, Volpato instead had a change of heart and switched nationalities to play for Tony Popovic’s side.

He had previously knocked back then coach Graham Arnold’s offer to play at the 2022 World Cup.

Volpato said he had tears in his eyes walking out ahead of his debut against the United States last month.

“If I knew about this, I would have come a long time ago,” he said.

Volpato was cut from academies at A-League sides Sydney FC and Western Sydney Wanderers before moving to Italy as a teenager, beginning his rise at football giants Roma.

“Growing up in Australia and playing for the two best academies in Sydney, I got told from both of them that basically I’m not good enough to play and I just felt like it was my time to just — I don’t know,” he said.

“I’ve always wanted to go to Italy as a kid so I think it came out perfectly to be honest.

“Because then straight after I just remember the car ride home with my dad, I was crying and he just said ‘don’t worry, we’ll go to Italy now and we’ll try it’.

“My mum, she sold her shop, we leased our house, we left everything just to go for a trial. And thank God I made the trial and my life changed from there.

“So I feel like I have to give a lot as well to Italy because they gave me a second opportunity and from there I also got picked for the Italian team first so I just accepted. So yeah, that’s basically it.”
