Norway 3 Nigeria 0
Ada Hegerberg was not needed as Norway kicked off their Women's World Cup Group A campaign with a comprehensive 3-0 victory over Nigeria on Sunday morning (AEST).
Without Ballon d'Or winner Hegerberg, who quit international football in 2017 due to a dispute with her home federation, the 1995 champions relied on goals by Guro Reiten, Lisa-Marie Karlseng Utland and an own goal by Osinachi Phale to prevail.
The result put Norway in second place in Group A behind hosts France, who thrashed South Korea 4-0 in the opening game of the month-long tournament in Paris.
Reiten put Norway in front after 17 minutes when she volleyed home from a corner.
Utland doubled the tally with a powerful shot from close range after being set up by Reiten in the 34th.
Three minutes later, three-times African champions Nigeria were completely overwhelmed as Ohale deflected Isabell Herlovsen's cross into her own goal.
Norway next face France in Nice on Thursday morning (AEST) while Nigeria take on South Korea in Grenoble earlier on Wednesday night.
Spain 3 South Africa 1
Jennifer Hermoso netted two second-half penalties and substitute Lucia Garcia added a last-minute goal as Spain came from behind to beat South Africa 3-1.
Hermoso tucked away spot-kicks in the 69th and 82nd minutes to give Spain a winning start to their Group B campaign after South Africa, in their maiden appearance at the finals, took a surprise first-half lead.
The first penalty came after a handball by South Africa captain Janine van Wyk and the second after follow through tackle by full back Nothando Vilakazi on Garcia which earned Vilakazi a second yellow card and a dismissal.
South Africa were on for a shock win after Thembi Kgatlana struck a powerful shot from the corner of the penalty area over the head of Spain goalkeeper Sandra Panos in the 25th minute.
The goal came after the South Africans had weathered Spain’s early dominance with desperate defending and then began to look threatening on the counter-attack.
African Women’s Footballer of the Year Kgatlana could have made it 2-0 but fluffed a tap-in opportunity at the back post in the 57th minute, not long after Hermoso had come close to an equalizer by striking the crossbar.
But Spain’s superior fitness saw them dominate the last half hour and there were other chances for a more commanding scoreline.
Garcia’s goal came from a ball straight down the middle of the pitch as she outsprinted the defence.
Germany 1 China 0
Germany's teenage midfielder Giulia Gwinn scored a second-half winner as the two-time world champions edged past China 1-0 to kick off their World Cup campaign.
The 19-year-old fired in from the edge of the box in the 66th minute to break stiff Chinese resistance in the Group B encounter.
China had almost stunned the favourites against the run of play in the first half when Yang Li was sent through after a German error but her shot was cleared when she looked certain to score.
Carolin Simon hit the woodwork with a cross minutes later but Germany's early dominance faded as the Chinese gained in confidence.
China earned another golden chance from a quick break, hitting the post in the 44th minute before Germany keeper Almuth Schult came to the rescue.
Gwinn then found just enough space in a crowded Chinese defence to fire home a cleanly-struck shot past keeper Peng Shimeng to settle the game.
Germany are now unbeaten in their last 13 matches, the longest run of any team taking part in the tournament in France. They next take on Spain on Thursday morning (AEST), while China play South Africa on Friday morning.
