Nigerian captain Ebi a mirror to Canada's Sinclair as teams prepare to clash in Women's World Cup

The Canadian team's motto for this Women's World Cup is "climb the mountain."

Canada begins that metaphoric climb Thursday night (10:30 p.m. ET) when they face Nigeria, a skilled and storied team that is the most decorated squad in Africa.

This is Nigeria's ninth World Cup appearance and they boast some phenomenal players. Known as the Super Falcons, the team also shares some fascinating similarities with Canada beyond technical capability and the power on the pitch. Their captains have achieved incredible accomplishments, and both teams have faced off against their federations in pursuit of equitable (aka better) treatment. 

Canada's Christine Sinclair and Nigeria's Onome Ebi are both 40 years old and playing in their sixth Women's World Cup. They are among the footballing legends who have brought history and greatness to the game. 

The two captains play with passion and have deep histories in shaping sport in their respective countries. Sinclair's impact on Canadian soccer cannot be overstated and her self-declared mission has been to "leave soccer in a better place than I found it," something she reiterated to media after the teams's final practice session before Thursday's game in Melbourne.

Her impact is global and her dedication to not only being the best player but most exceptional leader for the Canadian team is undeniable.

"[Sinc] is incredibly good at the game of soccer, pretty much better than anyone on Earth," wrote former teammate Diana Matheson, "... and she has devoted her life to it. In doing so, she became an exceptional leader and teammate to all those around her."
