Fonua's numbers across five U20 Championship matches paint a picture of a lock who earns his minutes through sheer consistency — rarely spectacular, but reliably present on both sides of the ball. His carry and tackle averages hold firm across the tournament, and his best outings show a capacity to step up his workload significantly when the game demands it. He is the kind of forward who keeps the engine running.
