Gelson Dala scored twice as Angola shrugged off the early dismissal of goalkeeper Neblu to beat 10-man Namibia and reach the quarter-finals of the 2023 Africa Cup of Nations.

Neblu was shown a straight red in the 17th minute for handling Bethuel Muzeu's shot outside his box, but Dala put Angola in front with a tap-in seven minutes before the break.

Namibia defender Lubeni Haukongo was soon sent off for a second bookable offence and two minutes later Dala doubled Angola's lead by powerfully heading home Fredy's free-kick.

Mabululu's neat finish following a swift counter-attack midway through the second half wrapped up victory and sent the Palancas Negras into the last eight for the first time since 2010.

Angola will face Nigeria in the next round in Abidjan on Friday (17:00 GMT) after the Super Eagles beat Cameroon 2-0.

Neblu had been booked for handling a through ball outside his area in Angola's group-stage win over Burkina Faso, but referee Dahane Beida had no choice but to send off the 30-year-old in Bouake
