Many in the 21-member team, playing in the first ever FIFA event to be held in the country from October 6-28, had seen their parents struggle to make ends meet.
But they have managed to pursue their passion for the game and are on the verge of realising a dream -- that of playing for the country at one of the biggest stages in international football.
"My parents are tailors and we have a small shop at my native place. When I was a child I used to play with round objects made of cloth or plastic," Thatal told PTI from the training base in Goa.
His father, Arun Kumar, and mother Sumitra have been saving from their meagre income to buy the playing kits for Thatal, including a pair of boots and a football.

From his local school at Timberbong at Soren sub-division in West Sikkim, Thatal made it to the Namchi Sports Academy in 2011. Impressed by his skills, the academy's head coach sent Thatal for a trial in 2014 in Goa when the AIFF was looking for talented players for the U-17 World Cup.
A similar struggle was endured by Amarjit Singh Kiyam, a Manipuri boy who is likely to captain the side in the U-17 World Cup.
Amarjit's father -- Chandramani Singh Kiyam is a farmer and carpenter rolled into one at Thoubal, a small town in Manipur. His mother Ashangbi Devi sells fish everyday at the state capital in Imphal, which is about 25 km from her home.
The 16-year-old fell in love with football at his local school and in 2010, he left for Chandigarh where his elder brother Umakanta Singh was enrolled at a football academy.
Amarjit joined Chandigarh Football Academy and that lessened the burden on his parents. The academy provided him free lodging, food and even bore the cost of education at a school in Chandigarh.
In 2015, during one of the exposure trips of CFA to Goa, Amarjit caught the eye of the national selectors. He was called at the AIFF Academy in Goa and since then he has been training there. He is the midfield general of the Indian team.
"Everyday my father goes out for some work or the other and so my mother stands and sells clothes at the footpath with my maternal uncle and that is our family's income. When I was a child I did not know where these booths are coming from nor did I know that the money came from selling clothes on the footpath. I just played football which was my passion.
Most of the remaining members of the Indian team are from humble backgrounds. Midfileder Khumanthem Ningthoinganba's mother also sells fish in Imphal while Kolkata boy Jitendra Singh's father is a watchman and mother a tailor.
All these young talents have the passion for football and same goal -- that of doing the country proud and making it to the national senior team one day.
"I used to think that one day I will represent the country and I am here now about to play in the U-17 World Cup. I still cannot believe it because it all feels like a dream," said Amarjit.
Sikkim boy Thatal summed it up nicely, saying, "Every footballer would want to play in the senior national team. But for us, it is the U-17 World Cup first. Our focus is on that. We will give our best, give our 100 per cent and hopefully do the country proud.
