In a break from training for one of the world's largest soccer tournaments, Yakub Ali swells with pride at the idea of putting a smile on the face of his mother back in Asia's biggest red light district.

"We've grown used to people sneering about where we come from and telling us that our mothers are worthless," says 15-year-old Yakub.

"So this will be a gift to all of our mothers who have to put up with discrimination, abuse and injustice every day of their life in Sonagachi."
