His older brother George Timotheou recently made his debut for A-League glamour team Sydney FC, but 15-year-old Antoni will get a rare opportunity next week to take on some of the world's most powerful clubs.
Antoni Timotheou is one of six ACT juniors selected in a combined NSW-ACT squad, coached by former Socceroos captain Craig Foster, that will represent Australia in a 10-team South Korean tournament.
Timotheou, Vuk Vukic, Ross Costanzo, Sam Smith, Tom Krklec and Ridwan Hannan will take on youth academy sides from some of the world's biggest clubs, including La Liga's Barcelona FC, the English Premier League's Tottenham Hotspur and Germany's Borussia Dortmund.
All six of the ACT's touring players have been selected from Canberra's National Training Centre development squad.
"You only have to take a look at the calibre of teams that have entered the competition to see how much of an opportunity this is for the group," Capital Football technical director Warren Grieve said. "This is a reward for their efforts."
Canberra's George Timotheou, 17, has been trialling with Sydney FC for a youth contract and recently made his debut for the Sky Blues in a pre-season trial.
Antoni, 15, said his brother's rise and his own selection in the Australian touring team has opened his eyes to the increasing opportunities for Canberra's young soccer players.
"He [George] has ... inspired me more now that he is with Sydney," Antoni said. "It shows me that anyone from Canberra can go that extra step [and] not just stay in Canberra. [Capital Football] has opened all these opportunities for me.
"I think we are gaining more respect among Australia in a football sense. Normally, [Football NSW] would just take their own players instead, but they [have] seen that we are as good as them."
