Opa Sangante's own goal earned Nigeria a 1-0 win over Guinea-Bissau as they sealed their spot in the last 16 as runners-up in the group.
The Super Eagles went ahead after 36 minutes when Sangante put through his own net but were unable to capitalise on a series of good chances to extend their lead, with Victor Osimhen going close multiple times.
The loss capped off a miserable campaign for already-eliminated Guinea-Bissau, who threatened Nigeria in the final stages but finished with three defeats. Nigeria’s Stanley Nwabali made the first save of the game from Nito Gomes’ ambitious long-range effort, but the Super Eagles grew into the game, Joe Aribo’s powerful strike taking a deflection and giving Jonas Mendes a routine stop.
Nigeria went in front when Moses Simon whipped in a dangerous cross intended for Osimhen and Sangante smashed the ball into the roof of his own net. They had a great chance to double the lead just before half-time as an unmarked Osimhen headed wide and threatened again two minutes into the second half when Mendes smothered Simon’s shot.
An action-packed start saw Osimhen’s headed effort loop wide and Dalcio had his low strike saved at the other end before Osimhen had an effort ruled out for offside.
Guinea-Bissau threatened in the final 10 minutes when Fali Cande’s free-kick took an awkward bounce, but Nwabali managed to push it wide before Gomes headed wide from the resulting corner. The late pressure almost paid off as a ferocious strike from Franculino Dju was ruled out for offside and Nigeria managed to see the game out.
