The Black Stars of Ghana booked a place into the semi-final of the ongoing AFCON 2017 in Gabon after the Stars beat DR Congo 2-1 in the quarter-final.
The first half of the game ended goalless but the Black Stars came back stronger and more efficient.
Jordan Ayew latched onto a pass from Mubarak Wakaso, beat a defender and fired past the goalkeeper to give the Black Stars the lead in the second half. The lead lasted only 7 minutes as Mpoku, fired in a beauty for the Congolese from just outside the penalty area.
Jordan and his elder brother Andre scored the pair of second half goals with Paul-Jose M'Poku's consolation goal in between.
The Black Stars were playing without talisman Asamoah Gyan who is picked up an injury in the final Group D match against Egypt.
Since 2008 when Ghana hosted the tournament, they have reached the medal zone of every other Nations Cup they have played in.
The Black Stars will meet Cameroon, who beat favourites Senegal 5-4 on penalties, in Thursday's second semi-final in Franceville.
