Their eyes lit up, their feet were mimicking famous moves and every so often, they turned over their left shoulder to see what their teammates were doing on the pitch behind them.
For four days starting next Tuesday, Alldan Chan, Zac Chng and Tyler Yap will fly the Republic's flag in Barcelona, where two teams of 12 youngsters from FCBEscola (FCBE) Singapore will take on other kids from around the world, all trained in the way of the famed Spanish giants.
The third edition of the annual FCBEscola International Tournament (April 15 to 18), a seven-a-side tourney for kids across four age groups, will take place a stone's throw away from the storied Nou Camp, and the Singapore trio cannot wait to strut their stuff.
On one side of the FCBE St Patrick's School headquarters was a giant banner with the faces of Nou Camp heroes Lionel Messi, Andres Iniesta and Xavi Hernandez, but the local youngsters needed no reminder that they will be in Barcelona, within touching distance of football greatness.
Alldan, 10, told The New Paper: "It'll be great if I can see Messi, Neymar and Iniesta, and get a chance to go to the place where they train.
"I'm serious about football, and I know that if we want to be good, we can't stop training and must practice as much as we can - like Messi."
While the Argentinian is also Zac's football idol, the 10-year-old's dream involves the Singapore flag.
"Singapore is my home and I want to be a national player and represent the country," he said, with his two teammates echoing his sentiments.
