Nigeria's Olympic Eagles must overturn a two-goal deficit against DR Congo in Ikenne on Tuesday, and only a three-goal winning margin takes them through to the final round of U23 AFCON qualifying without a penalty shootout.
DR Congo won the first leg 2-0 at the TP Mazembe Stadium in Lubumbashi on Friday, with goals in the 15th and 36th minutes. Reports differ on who was credited with the opener, which Nigeria's players disputed, while Filozofe Mabete scored the second.
The first leg went ahead in Lubumbashi despite the Ebola concerns that clouded the fixture, and it left Nigeria with a long way back.
What Tuesday asks of the Olympic Eagles
The return leg is at the Remo Stars Stadium in Ikenne on Tuesday 17 November. A two-goal Nigeria win would level the tie and send it to penalties, a three-goal win would settle it outright, and DR Congo need only avoid defeat.
Winger Zadok Yohanna was forced off in Lubumbashi, and midfielder Daniel Daga was booked in the 70th minute. The winner goes into the final qualifying round for the 2027 U23 AFCON in Egypt, the tournament that also decides Africa's places at the 2028 Olympic Games in Los Angeles. Nigeria, Olympic champions at Atlanta 1996, missed the last two men's tournaments.

Analysis: Why the first goal in Ikenne matters most
A three-goal margin is a big ask against a side that scored twice before half-time on Friday. The maths leaves no room for patience: an early goal turns Ikenne into a pressure cooker for the visitors, while a goalless first half would shrink the time Nigeria have for the rest.
The away side's position cuts the other way too. Every DR Congo goal raises the bar again, so Nigeria must push numbers forward without leaving the space for a counter-attack that would all but end the tie. The balance between attack and protection in midfield will decide whether the comeback is still alive into the last half-hour.
Tuesday's first 20 minutes in Ikenne should tell whether the road to Los Angeles is still open.
