Fresh from leading Melbourne Victory to an A-League championship, Troisi is determined to go to his second straight World Cup after playing in two of Australia's three group stage games at Brazil 2014.
The attacking midfielder was also one of the standout performers for the Socceroos during the 2017 FIFA Confederations Cup in Russia and scored the goal which clinched the AFC Asian Cup for his country two years earlier.
However, with a new coach in charge of the Socceroos, and places in the squad at a premium, the 29-year-old knows his ticket to Russia isn’t guaranteed.
"That’s how football goes. Obviously some boys who have been involved with the squad for years have missed out and there will be another three cut from the squad before the World Cup," Troisi said.
"Everyone is fighting for their spot and we will be pushing each other to earn our place on the team.
"We have a good group and everyone respects each other but competition will be fierce.
"While individually you are trying to impress, everyone knows we need work together to be successful. We will get the gaffer’s message and see how we can put it together in the friendlies."
Socceroos World Cup selection would be the icing on the cake for Troisi after what has been an impressive season for the Adelaide product.
Troisi is confident in his form coming into camp and believes his A-League success would help his performances for the national team.
"My preparation for this camp has been great," he said.
"I have played close to 40 games this season and coming into camp after winning the A-League is massive for me as well.
"Physically it is the best I have ever felt so I am raring to go for what will be a tough camp.”
While many are tipping the Socceroos to struggle, after being drawn in a tough group against France, Denmark and Peru, Troisi said Australia has the toughness and experience to taste success in Russia.
"We've all been in this situation and we've experienced so much as a group and as a team, so we've got some experienced players now and everyone's sort of been in that situation whether it's the World Cup, Asian Cup or the Confeds Cup," Troisi said.
"We've been at these high-quality and pressure tournaments and situations, so we'll definitely want to take that into what's going to be a fantastic World Cup.”
