While only victory would be enough for Cameroon to stand a chance of progression, Chile knew that they would progress if they avoided defeat, regardless of the drawing result at the same venue.
However, the 0-0 draw in the second leg of the playoff - as the Chileans claimed a 2-1 win on aggregate to ensure they secured their first-ever qualification ticket to the Olympic Games this summer.
Nchout and Gabrielle Onguene came close for the visitors but the Atletico Madrid star failed to put the ball past Chile goalkeeper Christiane Endler.
On the other hand, the Chileans enjoyed their positive moments in front of goal when Yanara Aedo and Guerrero came close but Cameroon goalkeeper Michaely Bihina did well to halt them.
