The players, toting Phoenix bags and mini-footballs as prizes for the best questions, were relaxed and engaged throughout the visit and their question-and-answer session at the revamped Greytown School hall, Mr Butler-Peck said.
Italiano, from Australia, described his life as a professional footballer as "awesome" and recalled the call from Phoenix coach Ernie Merrick asking him to sign for the Wellington club.
Spaniards Riera and Gorrin talked about growing up in their home country and how hard work at training helped them achieve their dreams of being professional footballers.
Greytown School sports co-ordinator Paul Hammond arranged for students who played football this season to meet the players, before a group of Year 7 and 8 pupils enjoyed a game against their heroes.
"I thought our players gave them a good test. The smiles on the kids' faces said it all."
Mr Butler-Peck said Wellington Phoenix were aiming to "spread their wings and build a football family across the whole region, and there's no doubt they left Greytown with scores of young supporters for life".
"When the Phoenix kick off their season against Perth Glory on October 12, there's sure to be lots of Wairarapa faces in the crowd," he said.
