Cedric Bakambu secured DR Congo's qualification for 2019 Africa Cup of Nations with his goal that gave them a 1-0 victory over Liberia on Sunday.
Following a goalless first half, the 27-year-old broke the deadlock in Kinshasa with his 57th-minute effort that handed Florent Ibenge's side maximum points to finish ahead of their visitors.
The victory made them the second team, after Zimbabwe, to qualify from Group G for the 2019 Afcon finals scheduled to commence later in June.
DR Congo concluded their qualifying campaign nine points from six games, two points behind leaders Zimbabwe.
