Argentina international Matera scored his first try for the club in Friday night’s LV= Cup clash with Bath Rugby.
He said teammate Tom Bristow played a big part in the try, helping maintain the momentum which took him over the line.
“I shouted when I scored,” said Matera. “It was a very good feeling. You never know how it will be when you score your first try but it was very emotional for me.
“I had some help from Bristow. I felt him pushing me and thought let’s get some more steps and I managed to reach out for the line.”
Matera was cheered on by members of the Buenos Aires Cricket and Rugby Club and the Belgrano Athletic Club, who took in the Anglo-Welsh fixture during a rugby tour to England.
The 20-year-old and Juan Pablo Orlandi, Bath’s Argentinean prop, joined the tourists at the front of the Goldsmiths Stand after the final whistle, posing for photos and signing autographs.
Matera said: “I heard a shout on the field during the match and though that it was not an English shout, that it was an Argentinean one!
“I realised it was the club. I played against some of them back home in Argentina.
“After the match finished we went over to say hi to them and took some photos with them. It was nice to see them at the game.”
