Goalkeeper Chiamaka Nnadozie saved a penalty to help Nigeria secure a valuable 0-0 draw against Olympic champions Canada in their Women's World Cup opener on Friday in a result that threw the group wide open.

Nnadozie denied Christine Sinclair from the spot in the 50th minute with a low dive to her left as the Canada skipper missed out on becoming the first player to score in six World Cups in front of 21,000 fans at Melbourne Rectangular Stadium.
