Fiji 7s captain Osea Kolinisau will not only be playing for his country but also for his brother.
Kolinisau says his brother was his biggest motivation and the reason why he still loves 7s rugby.
He also says that his brother, Korovavala Kolinisau was more talented, and Kolinisau grew up watching him play rugby 7s.
Kolinisau says there is a lot of pressure to lead the Fiji 7s team to the Olympics.
