Northern Ireland boss Michael O'Neill hopes his young players learn from the "cruel" nature of international football following back-to-back Euro 2024 qualifying defeats.
From Callum Marshall's VAR dejection in Denmark, to Monday night's "sucker punch" against Kazakhstan, O'Neill's fledgling stars have been on the receiving end in recent days.
The national manager says fine margins can determine a country's qualifying fate, with the past week's results highlighting the size of the challenge facing his squad in Group H.
