Boris Singh has steadily matured as a player since he led Manipur to the U14 national championship title in 2013. He has represented India in the AFC U16 Championship and subsequently at the world stage when the country hosted the U17 World Cup in 2017.
However, from a very young age, he has learnt that failures will teach you more than success. He was rejected by the All India Football Federation's (AIFF) Elite Academy when he first appeared for trials. But a more chastening incident took place in the AFC U16 Championship match against Iran in Margao.
