Thangjam was a key member of India’s FIFA U-17 World Cup squad last season and subsequently attracted eyeballs with his impressive performances in the I-League.

Although he was a consistent performer for Indian Arrows for two seasons, the youngster is yet to make his first-team debut for ATKMB in the ISL.

Thangjam had appeared for the team’s reserve side last season in the Durand Cup.

Thangjam had been earmarked as a huge talent ever since he caught the All India Football Federation (AIFF) scouts’ eye after he led Manipur to the U14 national championship title in 2013.

Thangjam was also part of the India U20 team beat Argentina 2-1 in the COTIF tournament in Spain under Floyd Pinto’s tutelage.
