Congo beat Burkina Faso 2-0 on Saturday to secure their spot in the 2018 African Nations Championship quarter-finals, establishing a two-point cushion over Angola at the top of Group D.
Manager Barthelemy Ngatsono's side made it two wins from two, defeating Burkina Faso thanks to goals from Carof Bakoua and Kader Bidimbou.
That win came after Angola temporarily moved to the top of Group D following their narrow 1-0 defeat of Cameroon, extending their own unbeaten start to the tournament.
Captain Ricardo Job Estevao's 30th-minute penalty gave Angola their first win of CHAN 2018, and manager Srdjan Vasiljevic's men are still yet to concede a goal after 180 minutes.
