Fergus Guiry was playing for Seaford College against Eton at the Rosslyn Park sevens tournament when he caught the eye of the England coaches and they invited him to trial.
He earned his first contract in 2017 after impressing but first he needed to complete his A Levels in Business, PE, Psychology at the college.
His first England cap came that summer in Moscow in the Rugby Europe Championships where he scored a try in his first match against Belgium.
July that year saw Fergus help Team England to a silver medal at the 2017 Youth Commonwealth Games in the Bahamas and he was named captain for the gold medal match against Samoa.
And just a few months later, the fly half and full back was also skipper of the England U18s who won a bronze medal at the 2017 European Championships in Heidelberg.
Born in Chichester, West Sussex, Fergus joined Chichester Rugby Club at six years old and was part of the Harlequins academy set up between the ages of 14 and 16.
Fergus lifted the National U17 Cup in 2016 with Worthing after scoring the winning try in the last minute in the final.
The fly half was a 17-year-old when he moved to London Irish where he worked alongside Paul Hodgson.
A Brighton football fan, Fergus also enjoys watching tennis and once managed to watch the whole of Breaking Bad in a single week.
