Just a few minutes later Umar put Nigeria in front. Stanley Amuzie sent in a curling cross to Umar who placed his header past Linde.
Early on in the second half Sweden’s Linde was forced into multiple diving saves to prevent Nigeria from building on its lead.

Despite the small margin of victory, Nigeria dominated Sweden throughout. Nigeria had 10 shots on goal compared to Sweden's one and held 56 percent of the possession.
